技术领域technical field
本实用新型涉及一种冰蓄冷冷却系统的蓄冷槽。The utility model relates to a cold storage tank of an ice cold storage cooling system.
背景技术Background technique
冰蓄冷冷却系统是指深夜低谷电价时运行冷冻机制冰到蓄冷球内，然后白天高峰电价时利用这些冰制冷的蓄冷球进行热交换而达到降温的目的的一种制冷系统。The ice storage cooling system refers to a refrigeration system that operates the refrigerating machine to put ice into the cold storage ball when the electricity price is low at night, and then uses these ice-cooled cold storage balls for heat exchange during the daytime peak electricity price to achieve the purpose of cooling.
这种冰蓄冷冷却系统的原理是，首先深夜时间段利用便宜的深夜低谷电价时运行冷冻机冷却不冻液，已冷却的不冻液通过容纳多个蓄冷球的蓄冷槽，把装在蓄冷球内的结冰液冻结成冰。如果结冰过程结束，把上述已结冰的蓄冷球保存在隔热状态的蓄冷槽内，白天结冰液的冰开始融化，使不冻液降温，不冻液循环流向热交换机，从而把上述已结冰的蓄冷球的冷气用于供冷，继而能够减少或避免白天最大负荷时的供冷电力的使用负荷。The principle of this ice-storage cooling system is that firstly, the freezer is used to cool the antifreeze in the middle of the night when the cheap electricity price is low in the night, and the cooled antifreeze passes through the cold storage tank containing a plurality of cold storage balls, and the cold storage balls The icing fluid inside freezes into ice. If the icing process is over, store the above-mentioned frozen cold storage balls in the heat-insulated cold storage tank, and the ice of the freezing liquid will start to melt during the day, so that the antifreeze liquid will cool down, and the antifreeze liquid will circulate to the heat exchanger, thereby turning the above-mentioned The cold air of the frozen cold storage balls is used for cooling, and then the usage load of cooling power during the daytime maximum load can be reduced or avoided.
冰蓄冷供冷系统与其他供冷系统相比，可以连续以额定的满负荷运行，因此无负荷降，系统非常稳定且效率高，是以冰为蓄冷媒介的环保型供冷系统，是最近非常令人注目的尖端供冷系统。Compared with other cooling systems, the ice storage cooling system can continuously operate at the rated full load, so there is no load drop, the system is very stable and efficient, and the environmentally friendly cooling system uses ice as the cold storage medium. Eye-catching cutting-edge cooling system.
现有的冰蓄冷冷却系统的蓄冷槽通常由隔性能良好的地下建筑屋内填满同直径的多个蓄冷球组成。The cold storage tank of the existing ice cold storage cooling system usually consists of a plurality of cold storage balls with the same diameter filled in an underground building with good insulation performance.
在上述蓄冷槽的一侧安装投入不冻液的不冻液注入管，另一侧安装把经过蓄冷球的不冻液向外部排出的不冻液排出管。An antifreeze injection pipe for dropping antifreeze is installed on one side of the cold storage tank, and an antifreeze discharge pipe for discharging the antifreeze passing through the cold storage ball to the outside is installed on the other side.
另外，在蓄冷槽的上方形成能够在安装时把蓄冷球投入到内部的盖口，为了在投入蓄冷球后封闭盖口，在盖口安装顶盖。In addition, a cover opening is formed above the cold storage tank to put the cold storage balls into the interior during installation, and a top cover is installed on the cover opening to close the cover opening after putting in the cold storage balls.
虽然不同制造企业的蓄冷槽的形态有所不同，但是为了便于不冻液的流动，现有蓄冷球为基本上具有球状外廓的相同直径的蓄冷球，这些相同直径的蓄冷球在蓄冷槽内形成多层填充。Although the shapes of cold storage tanks of different manufacturers are different, in order to facilitate the flow of antifreeze, the existing cold storage balls are cold storage balls with the same diameter basically having a spherical outer shape. Form multiple layers of filling.
蓄冷球由在其内部形成中空的容器和容纳于蓄冷球内的结冰液组成。如果结冰液被不冻液冷却到冰点以下温度，能够在结冰时把不冻液的冷气以结冰液的冰形态蓄冷(能量储存)。The cold storage ball is composed of a hollow container formed inside the cold storage ball and freezing liquid accommodated in the cold storage ball. If the freezing liquid is cooled to a temperature below the freezing point by the antifreezing liquid, the cold air of the antifreezing liquid can be stored cold (energy storage) in the ice form of the freezing liquid when freezing.
如果深夜运行冷冻机，已经冷却的不冻液通过不冻液注入管流入到蓄冷槽内部，流到蓄冷球之间的空隙。蓄冷球内的结冰液被不冻液的冷气结冰蓄冷，与蓄冷球接触流动的不冻液通过上述不冻液排出管重新循环到冷冻机。If the freezer is operated late at night, the cooled antifreeze will flow into the cold storage tank through the antifreeze injection pipe, and flow into the gap between the cold storage balls. The freezing liquid in the cold storage ball is frozen and stored by the cold air of the antifreezing liquid, and the antifreezing liquid flowing in contact with the cold storage ball is recirculated to the refrigerator through the above-mentioned antifreezing liquid discharge pipe.
结冰过程结束后，已经结冰的蓄冷球储存在隔热状态的蓄冷槽内，白天循环不冻液，热交换机用上述已经结冰的蓄冷球的冷气来供冷。After the icing process is over, the frozen cold storage balls are stored in the heat-insulated cold storage tank, the antifreeze is circulated during the day, and the heat exchanger uses the cold air from the frozen cold storage balls to provide cooling.
冰蓄冷冷却系统的上述供冷容量与在蓄冷槽内填充的蓄冷球的体积，即冰的体积有密切关系，如果在蓄冷槽的内部中蓄冷球的体积(充填率)越高，蓄冷量就越大。The above-mentioned cooling capacity of the ice storage cooling system is closely related to the volume of the cold storage balls filled in the cold storage tank, that is, the volume of ice. If the volume (filling rate) of the cold storage balls in the cold storage tank is higher, the cold storage capacity will be higher. bigger.
但是，为了提高这种供冷容量，因受到建筑物大小和制作费的限制，不能无限制地提高上述蓄冷槽的体积。But, in order to improve this cooling capacity, because be subjected to the limitation of building size and manufacturing cost, can not improve the volume of above-mentioned cold storage tank without limit.
另外，虽然可以考虑为了提高充填率而制作非常细小尺寸的蓄冷球，但在一定体积内的相同直径球体所占体积与其球体的直径或个数无关，而是始终恒定(充填率始终相同)，这是众所周知的实事。In addition, although it is conceivable to make very small-sized cold storage balls in order to increase the filling rate, the volume occupied by spheres with the same diameter within a certain volume has nothing to do with the diameter or number of spheres, but is always constant (the filling rate is always the same), This is a well-known fact.
因此，具有相同直径蓄冷球的冰蓄冷冷却系统的蓄冷槽不能提高蓄冷球的充填率，因此冰蓄冷冷却系统的供冷容量少，为了增加供冷量，现有的冰蓄冷冷却系统的蓄冷槽体积增大，在建筑物中所占的体积增大，即相同高度的蓄冷槽所占的底面面积只能非常大。Therefore, the cold storage tank of the ice cold storage cooling system with the same diameter cold storage balls cannot increase the filling rate of the cold storage balls, so the cooling capacity of the ice cold storage cooling system is small. In order to increase the cooling capacity, the cold storage tank of the existing ice cold storage cooling system As the volume increases, the volume occupied in the building increases, that is, the area of the bottom surface occupied by the cold storage tank of the same height can only be very large.
另外，上述冰蓄冷冷却系统的供冷性能是在开始融化冰时发挥出来的，由于相同体积的冰同时从以前的相同直径的蓄冷球的表面开始融化，没有增加冰的表面积的方法，因此不能加快融冰速度，存在不能提高供冷性能的问题。In addition, the cooling performance of the above-mentioned ice storage cooling system is brought into play when the ice starts to melt. Since the ice of the same volume starts to melt from the surface of the previous cold storage ball with the same diameter at the same time, there is no way to increase the surface area of the ice, so it cannot There is a problem that cooling performance cannot be improved by increasing the ice-melting speed.
因而，如何提高蓄冷球的充填率，成为提高蓄冷槽的蓄冷量和冷却效率的关键。Therefore, how to increase the filling rate of the cold storage balls becomes the key to improving the cold storage capacity and cooling efficiency of the cold storage tank.
实用新型内容Utility model content
本实用新型需要解决的技术问题就在于克服现有蓄冷槽内具有相同直径蓄冷球、不能提高蓄冷球的充填率的缺陷，提供一种冰蓄冷冷却系统的蓄冷槽，它在大直径的主蓄冷球之间安装直径小的辅助蓄冷球，提高了蓄冷球的填充率，从而能够提高蓄冷系统的蓄冷量和冷却效率。The technical problem to be solved by the utility model is to overcome the defect that the cold storage balls with the same diameter in the existing cold storage tank cannot improve the filling rate of the cold storage balls, and provide a cold storage tank for the ice storage cooling system. Small-diameter auxiliary cold storage balls are installed between the balls to increase the filling rate of the cold storage balls, thereby improving the cold storage capacity and cooling efficiency of the cold storage system.
为解决上述问题，本实用新型采用如下技术方案：In order to solve the above problems, the utility model adopts the following technical solutions:
本实用新型一种冰蓄冷冷却系统的蓄冷槽，包括蓄冷槽和填充在蓄冷槽内的蓄冷球，蓄冷槽上部的一侧设置有不冻液注入管，蓄冷槽下部的另一侧设置有不冻液排出管，所述蓄冷球为不同直径的蓄冷球。The utility model relates to a cold storage tank of an ice cold storage cooling system, which comprises a cold storage tank and a cold storage ball filled in the cold storage tank. One side of the upper part of the cold storage tank is provided with an antifreeze injection pipe, and the other side of the lower part of the cold storage tank is provided with a non-freezing pipe. The frozen liquid discharge pipe, the cold storage balls are cold storage balls with different diameters.
本实用新型所述蓄冷球由大直径的主蓄冷球和相对小直径的辅助蓄冷球构成，在相邻的主蓄冷球和主蓄冷球之间的空隙内填充辅助蓄冷球。The cold storage ball in the utility model is composed of a large-diameter main cold storage ball and a relatively small-diameter auxiliary cold storage ball, and the auxiliary cold storage ball is filled in the gap between the adjacent main cold storage ball and the main cold storage ball.
本实用新型所述蓄冷槽顶部设置有蓄冷球注入口，所述注入口安装顶盖。The top of the cold storage tank of the utility model is provided with a cold storage ball injection port, and a top cover is installed on the injection port.
优选的，本实用新型所述主蓄冷球的直径为8cm-15cm，所述辅助蓄冷球的直径为1cm-6cm。Preferably, the diameter of the main cold storage ball in the present invention is 8cm-15cm, and the diameter of the auxiliary cold storage ball is 1cm-6cm.
本实用新型蓄冷槽内填充不同直径的蓄冷球，它提高了蓄冷球的充填率，增加冰蓄冷冷却系统的供冷容量，减少了蓄冷槽的体积，从而减少蓄冷槽的安装费及维护费。由于最大限度地增加不冻液能够与冰接触的面积，即冰的表面积，从而加快冰的冷却速度和融冰速度，因此具有能够提高冰蓄冷供冷系统的冷却性能的效果。The cold storage tank of the utility model is filled with cold storage balls of different diameters, which improves the filling rate of the cold storage balls, increases the cooling capacity of the ice cold storage cooling system, reduces the volume of the cold storage tank, thereby reducing the installation cost and maintenance cost of the cold storage tank. Since the area where the antifreezing liquid can be in contact with the ice is maximized, that is, the surface area of the ice, the cooling speed and melting speed of the ice are accelerated, so it has the effect of improving the cooling performance of the ice storage cooling system.
考虑到主蓄冷球的冰的容量等，本实用新型所述主蓄冷球的直径高于8cm，其直径达到更合适的8cm-15cm时，所述辅助蓄冷球的直径低于6cm，更合适的其直径为1cm-6cm。Considering the ice capacity of the main cold storage ball, etc., the diameter of the main cold storage ball described in the present invention is higher than 8cm, and when the diameter reaches a more suitable 8cm-15cm, the diameter of the auxiliary cold storage ball is lower than 6cm, which is more suitable Its diameter is 1cm-6cm.
所述主蓄冷球和辅助蓄冷球由在其内部形成中空的容器和收容于容器内的结冰液组成。如果结冰液被不冻液冷却到冰点以下温度，能够在结冰时把不冻液的冷气以结冰液的冰形态蓄冷(能量储存)。The main cold storage ball and the auxiliary cold storage ball are composed of a hollow container inside and a freezing liquid accommodated in the container. If the freezing liquid is cooled to a temperature below the freezing point by the antifreezing liquid, the cold air of the antifreezing liquid can be stored cold (energy storage) in the ice form of the freezing liquid when freezing.
安装蓄冷槽时打开顶盖，主蓄冷球和辅助蓄冷球在收容不冻液的蓄冷槽内部同时落下，互相混合，在主蓄冷球之间自然能够安装辅助蓄冷球。When the cold storage tank is installed, the top cover is opened, and the main cold storage balls and the auxiliary cold storage balls fall simultaneously in the cold storage tank containing the antifreeze and mix with each other, and the auxiliary cold storage balls can naturally be installed between the main cold storage balls.
深夜运行冷冻机，已经冷却的不冻液通过不冻液注入管流入到蓄冷槽内部，流到主蓄冷球和辅助蓄冷球之间的空隙。主蓄冷球和辅助蓄冷球内的结冰液被不冻液的冷气结冰蓄冷，与主蓄冷球和辅助蓄冷球接触流动的不冻液通过不冻液排出管重新循环到冷冻机。When the freezer is running late at night, the cooled antifreeze flows into the cold storage tank through the antifreeze injection pipe, and flows into the gap between the main cold storage ball and the auxiliary cold storage ball. The freezing liquid in the main cold storage ball and the auxiliary cold storage ball is frozen and stored by the cold air of the antifreeze liquid, and the antifreeze flowing in contact with the main cold storage ball and the auxiliary cold storage ball is recirculated to the refrigerator through the antifreeze discharge pipe.
此时，不冻液通过由主蓄冷球和辅助蓄冷球构成的细小通道，辅助蓄冷球不仅提高充填率，同时增加蓄冷球的表面积即冰的表面积，从而能够达到按照从辅助蓄冷球到主蓄冷球的顺序快速冻结和快速融化。At this time, the antifreeze passes through the small channel formed by the main cold storage ball and the auxiliary cold storage ball. The auxiliary cold storage ball not only improves the filling rate, but also increases the surface area of the cold storage ball, that is, the surface area of ice, so that The order of the balls is quick freeze and quick thaw.
结冰过程结束，上述已经结冰的蓄冷球储存在隔热性能良好的蓄冷槽内，白天循环不冻液，热交换机利用已经结冰的蓄冷球的冷气供冷。After the freezing process is over, the above-mentioned frozen cold storage balls are stored in the cold storage tank with good heat insulation performance, and the antifreeze is circulated during the day, and the heat exchanger uses the cold air of the frozen cold storage balls for cooling.
本实用新型冰蓄冷冷却系统的蓄冷槽的供冷容量与在蓄冷槽内填充的蓄冷球的体积，即冰的体积有密切关系，如果在蓄冷槽内蓄冷球的体积(充填率)越高，蓄冷量就越多。The cooling capacity of the cold storage tank of the ice cold storage cooling system of the utility model is closely related to the volume of the cold storage balls filled in the cold storage tank, that is, the volume of ice. If the volume (filling rate) of the cold storage balls in the cold storage tank is higher, The more cold storage capacity.
因此，本实用新型的蓄冷槽在主蓄冷球之间充填辅助蓄冷球，根据辅助蓄冷球所充填的体积，冰的体积也随之增加，因此提高充填率，最大限度地提高蓄冷槽所能蓄冷的蓄冷量，同时增加冰的表面积，从而可以按照从辅助蓄冷球到主蓄冷球的顺序快速结冰和融冰，即能够提高在特定时间内供给建筑物的供冷量。Therefore, the cold storage tank of the utility model is filled with auxiliary cold storage balls between the main cold storage balls. According to the volume filled by the auxiliary cold storage balls, the volume of ice will also increase accordingly, thereby increasing the filling rate and maximizing the cold storage capacity of the cold storage tank. At the same time, the surface area of the ice is increased, so that the ice can be quickly frozen and melted in the order from the auxiliary cold storage ball to the main cold storage ball, that is, the cooling capacity supplied to the building within a specific time can be increased.
本实用新型的蓄冷槽经效果试验证明：安装在同等容积的蓄冷槽内，填充直径为12.5cm的主蓄冷球与混合直径为3.5cm的辅助蓄冷球，其结果，充填率比以前只采用主蓄冷球的情况(充填率约50％)提高约10％增加到约60％。随着冰的表面积的增加，供冷性能约增加20％。尤其是，同等蓄冷量蓄冷槽建筑物的底面面积可从以前的19m2减少到14m2，这将减少35％的底面面积，具有比以前的任何性能改善办法更优越的效果。The cold storage tank of the utility model has been proved by the effect test: it is installed in the cold storage tank of the same volume, and the main cold storage ball with a diameter of 12.5 cm is filled with the auxiliary cold storage ball with a diameter of 3.5 cm. The case of cold storage balls (fill rate about 50%) is increased by about 10% to about 60%. As the surface area of the ice increases, the cooling performance increases by approximately 20%. Especially, the bottom surface area of the cold storage tank building with the same cold storage capacity can be reduced from the previous 19m 2 to 14m 2 , which will reduce the bottom surface area by 35%, and has a superior effect than any previous performance improvement method.
本实用新型的不同直径蓄冷球的冰蓄冷冷却系统蓄冷槽提高了蓄冷球的充填率，从而增加冰蓄冷冷却系统的蓄冷槽的供冷容量，减少蓄冷槽的底面面积，减少制作费及安装费，大幅增加冰的表面积，因此更加加快结冰速度及融冰速度，大大提高供冷性能。The cold storage tank of the ice cold storage cooling system with different diameter cold storage balls of the utility model improves the filling rate of the cold storage ball, thereby increasing the cooling capacity of the cold storage tank of the ice cold storage cooling system, reducing the bottom surface area of the cold storage tank, and reducing the production cost and installation cost , greatly increasing the surface area of ice, so the speed of freezing and melting is accelerated, and the cooling performance is greatly improved.

具体实施方式Detailed ways
如图1所示，本实用新型一种冰蓄冷冷却系统的蓄冷槽，包括蓄冷槽1和填充在蓄冷槽内的蓄冷球，蓄冷槽内注有不冻液7，蓄冷槽上部的一侧设置有不冻液注入管3，蓄冷槽下部的另一侧设置有不冻液排出管4，所述蓄冷球为不同直径的蓄冷球，As shown in Figure 1, the cold storage tank of the ice cold storage cooling system of the utility model includes a cold storage tank 1 and a cold storage ball filled in the cold storage tank. There is an
本实用新型所述蓄冷球由大直径的主蓄冷球21和相对小直径的辅助蓄冷球22构成，在相邻的主蓄冷球和主蓄冷球之间的空隙内填充辅助蓄冷球。The cold storage ball in the utility model is composed of a large-diameter main
本实用新型所述蓄冷槽顶部设置有蓄冷球注入口5，所述注入口安装顶盖6。The top of the cold storage tank of the utility model is provided with a cold storage ball injection port 5, and a
优选的，本实用新型所述主蓄冷球的直径为8cm-15cm，所述辅助蓄冷球的直径1cm-6cm。Preferably, the diameter of the main cold storage ball in the present invention is 8cm-15cm, and the diameter of the auxiliary cold storage ball is 1cm-6cm.
本实用新型蓄冷槽内填充不同直径的蓄冷球，它提高了蓄冷球的充填率，增加冰蓄冷冷却系统的供冷容量，减少了蓄冷槽的体积，从而减少蓄冷槽的安装费及维护费。由于最大限度地增加不冻液能够与冰接触的面积，即冰的表面积，从而加快冰的冷却速度和融冰速度，因此具有能够提高冰蓄冷供冷系统的冷却性能的效果。The cold storage tank of the utility model is filled with cold storage balls of different diameters, which improves the filling rate of the cold storage balls, increases the cooling capacity of the ice cold storage cooling system, reduces the volume of the cold storage tank, thereby reducing the installation cost and maintenance cost of the cold storage tank. Since the area where the antifreezing liquid can be in contact with the ice is maximized, that is, the surface area of the ice, the cooling speed and melting speed of the ice are accelerated, so it has the effect of improving the cooling performance of the ice storage cooling system.
考虑到主蓄冷球的冰的容量等，本实用新型所述主蓄冷球的直径高于8cm，其直径达到更合适的8cm-15cm时，所述辅助蓄冷球的直径低于6cm，更合适的其直径为1cm-6cm。Considering the ice capacity of the main cold storage ball, etc., the diameter of the main cold storage ball described in the present invention is higher than 8cm, and when the diameter reaches a more suitable 8cm-15cm, the diameter of the auxiliary cold storage ball is lower than 6cm, which is more suitable Its diameter is 1cm-6cm.
所述主蓄冷球和辅助蓄冷球由在其内部形成中空的容器和收容于容器内的结冰液组成。如果结冰液被不冻液冷却到冰点以下温度，能够在结冰时把不冻液的冷气以结冰液的冰形态蓄冷(能量储存)。The main cold storage ball and the auxiliary cold storage ball are composed of a hollow container inside and a freezing liquid accommodated in the container. If the freezing liquid is cooled to a temperature below the freezing point by the antifreezing liquid, the cold air of the antifreezing liquid can be stored cold (energy storage) in the ice form of the freezing liquid when freezing.
安装蓄冷槽时打开顶盖，主蓄冷球和辅助蓄冷球在收容不冻液的蓄冷槽内部同时落下，互相混合，在主蓄冷球之间自然能够安装辅助蓄冷球。When the cold storage tank is installed, the top cover is opened, and the main cold storage balls and the auxiliary cold storage balls fall simultaneously in the cold storage tank containing the antifreeze and mix with each other, and the auxiliary cold storage balls can naturally be installed between the main cold storage balls.
深夜运行冷冻机，已经冷却的不冻液通过不冻液注入管流入到蓄冷槽内部，流到主蓄冷球和辅助蓄冷球之间的空隙。主蓄冷球和辅助蓄冷球内的结冰液被不冻液的冷气结冰蓄冷，与主蓄冷球和辅助蓄冷球接触流动的不冻液通过不冻液排出管重新循环到冷冻机。When the freezer is running late at night, the cooled antifreeze flows into the cold storage tank through the antifreeze injection pipe, and flows into the gap between the main cold storage ball and the auxiliary cold storage ball. The freezing liquid in the main cold storage ball and the auxiliary cold storage ball is frozen and stored by the cold air of the antifreeze liquid, and the antifreeze flowing in contact with the main cold storage ball and the auxiliary cold storage ball is recirculated to the refrigerator through the antifreeze discharge pipe.
此时，不冻液通过由主蓄冷球和辅助蓄冷球构成的细小通道，辅助蓄冷球不仅提高充填率，同时增加蓄冷球的表面积即冰的表面积，从而能够达到按照从辅助蓄冷球到主蓄冷球的顺序快速冻结和快速融化。At this time, the antifreeze passes through the small channel formed by the main cold storage ball and the auxiliary cold storage ball. The auxiliary cold storage ball not only improves the filling rate, but also increases the surface area of the cold storage ball, that is, the surface area of ice, so that The order of the balls is quick freeze and quick thaw.
结冰过程结束，上述已经结冰的蓄冷球储存在隔热性能良好的蓄冷槽内，白天循环不冻液，热交换机利用已经结冰的蓄冷球的冷气供冷。After the freezing process is over, the above-mentioned frozen cold storage balls are stored in the cold storage tank with good heat insulation performance, and the antifreeze is circulated during the day, and the heat exchanger uses the cold air of the frozen cold storage balls for cooling.
本实用新型冰蓄冷冷却系统的蓄冷槽的供冷容量与在蓄冷槽内填充的蓄冷球的体积，即冰的体积有密切关系，如果在蓄冷槽内蓄冷球的体积(充填率)越高，蓄冷量就越多。The cooling capacity of the cold storage tank of the ice cold storage cooling system of the utility model is closely related to the volume of the cold storage balls filled in the cold storage tank, that is, the volume of ice. If the volume (filling rate) of the cold storage balls in the cold storage tank is higher, The more cold storage capacity.
因此，本实用新型的蓄冷槽在主蓄冷球之间充填辅助蓄冷球，根据辅助蓄冷球所充填的体积，冰的体积也随之增加，因此提高充填率，最大限度地提高蓄冷槽所能蓄冷的蓄冷量，同时增加冰的表面积，从而可以按照从辅助蓄冷球到主蓄冷球的顺序快速结冰和融冰，即能够提高在特定时间内供给建筑物的供冷量。Therefore, the cold storage tank of the utility model is filled with auxiliary cold storage balls between the main cold storage balls. According to the volume filled by the auxiliary cold storage balls, the volume of ice will also increase accordingly, thereby increasing the filling rate and maximizing the cold storage capacity of the cold storage tank. At the same time, the surface area of the ice is increased, so that the ice can be quickly frozen and melted in the order from the auxiliary cold storage ball to the main cold storage ball, that is, the cooling capacity supplied to the building within a specific time can be increased.
本实用新型的蓄冷槽经效果试验证明：安装在同等容积的蓄冷槽内，填充直径为12.5cm的主蓄冷球与混合直径为3.5cm的辅助蓄冷球，其结果，充填率比以前只采用主蓄冷球的情况(充填率约50％)提高约10％增加到约60％。随着冰的表面积的增加，供冷性能约增加20％。尤其是，同等蓄冷量蓄冷槽建筑物的底面面积可从以前的19m2减少到14m2，这将减少35％的底面面积，具有比以前的任何性能改善办法更优越的效果。The cold storage tank of the utility model has been proved by the effect test: it is installed in the cold storage tank of the same volume, and the main cold storage ball with a diameter of 12.5 cm is filled with the auxiliary cold storage ball with a diameter of 3.5 cm. The case of cold storage balls (fill rate about 50%) is increased by about 10% to about 60%. As the surface area of the ice increases, the cooling performance increases by approximately 20%. Especially, the bottom surface area of the cold storage tank building with the same cold storage capacity can be reduced from the previous 19m 2 to 14m 2 , which will reduce the bottom surface area by 35%, and has a superior effect than any previous performance improvement method.
