Description
技术领域 technical field
本实用新型涉及一种用于空调机的节能型电热加湿系统。The utility model relates to an energy-saving electric heating humidification system for an air conditioner.
背景技术 Background technique
恒温恒湿空调机等工艺性空调机通常配置有电热加湿器，这种电热加湿器是通过电热元件使进入电加湿器器内的水汽化蒸发，并送至空调通风风道，提高空调出风湿度，最后实现空调场所等温加湿。由于这种电热加湿器的能耗占整个空调机总能耗的较大比例，因此，造成此类空调机的性能比非常低下。另外，由于电热加湿器的补水温度一般较低，仅通过电热元件将水加热升温至汽化的时间较长，导致加湿速度较慢。通常在补水后的很长时间内都无法加湿，导致空调机实际的湿度控制精度和速度效果不佳。Technological air conditioners such as constant temperature and humidity air conditioners are usually equipped with electric humidifiers. This kind of electric humidifier vaporizes and evaporates the water entering the electric humidifier through electric heating elements, and sends it to the air conditioning ventilation duct to improve the humidity of the air conditioner. Finally, achieve isothermal humidification in air-conditioned places. Since the energy consumption of such an electric humidifier accounts for a large proportion of the total energy consumption of the entire air conditioner, the performance ratio of this type of air conditioner is very low. In addition, since the water supply temperature of the electric humidifier is generally low, it takes a long time to heat the water to vaporization only through the electric heating element, resulting in a slow humidification speed. Usually, it cannot be humidified for a long time after replenishing water, which leads to the poor effect of the actual humidity control accuracy and speed of the air conditioner.
中国专利文献号CN25334.13Y中公开了一种工业用无尘省电型恒温恒湿机，主要包括有压缩机、冷凝器、蒸发器、电热器、加湿器、风车、初级滤网、高级滤网、冷却水泵、冷却水塔，其中，蒸发器前方设有初级滤网，蒸发器后方设有当热能不够时可补充的电热器及调整空气湿度的加湿器，其上方设有出风的风车及精密高级过滤网，而提供冷媒产生高压高温的压缩机及提供冷却的冷凝器一端分别与设有膨胀阀的蒸发器连接，冷凝器外则包覆设有由冷却水塔并由冷却水泵作循环的冷却水，其特征是：蒸发器与电热器间设有至少一个以上的热回收器，而下方设有电磁阀的热回收器一端与冷凝器另端连接，热回收器另端则与压缩机另端连接，以形成高压高温冷媒先经一个以上的热回收器将热回收而达冷凝器，或该冷媒利用电磁阀旁路直接达冷凝器的流通回路。这种恒温恒湿机的能耗比比较低且加湿效果不够理想。Chinese Patent Document No. CN25334.13Y discloses an industrial dust-free and power-saving constant temperature and humidity machine, which mainly includes a compressor, a condenser, an evaporator, an electric heater, a humidifier, a windmill, a primary filter screen, and a high-grade filter.

An energy-saving electric heating humidification system for air conditioners with humidification speed and temperature control accuracy of the whole machine, so as to overcome the deficiencies in the prior art.
按此目的设计的一种用于空调机的节能型电热加湿系统，包括压缩机、电加湿器、冷凝器和热回收器，其特征是压缩机的排气出口与两支路相接，其中一支路与冷凝器的一端相连通，另一支路与热回收器相连通；热回收器上分别设置有冷媒进口、冷媒出口、进水口和出水口，其中，冷媒进口与压缩机的排气出口相连通，冷媒出口与冷凝器的一端相连通，进水口与向电热加湿器供水的供水管相连通，出水口与电热加湿器的进水管相连通。An energy-saving electric heating humidification system for air conditioners designed according to this purpose, including a compressor, an electric humidifier, a condenser and a heat recovery device, is characterized in that the exhaust outlet of the compressor is connected to two branches, of which One branch is connected with one end of the condenser, and the other branch is connected with the heat recovery device; the heat recovery device is respectively provided with a refrigerant inlet, a refrigerant outlet, a water inlet and a water outlet. The gas outlet is connected, the refrigerant outlet is connected with one end of the condenser, the water inlet is connected with the water supply pipe for supplying water to the electric humidifier, and the water outlet is connected with the water inlet pipe of the electric humidifier.
所述两支路中设置有第一电磁阀和第二电磁阀，第一电磁阀和第二电磁阀分别与空调机的主控制器电连接；第一电磁阀串接在压缩机的排气出口和热回收器的冷媒进口之间，第二电磁阀串接在压缩机的排气出口和冷凝器的一端之间，冷媒出口接入第二电磁阀和冷凝器的一端之间。The two branches are provided with a first solenoid valve and a second solenoid valve, and the first solenoid valve and the second solenoid valve are respectively electrically connected to the main controller of the air conditioner; the first solenoid valve is connected in series to the discharge port of the compressor. Between the outlet and the refrigerant inlet of the heat recovery device, the second solenoid valve is connected in series between the exhaust outlet of the compressor and one end of the condenser, and the refrigerant outlet is connected between the second solenoid valve and one end of the condenser.
所述热回收器为罐状，换热盘管盘绕在热回收器内，换热盘管的两端分别为冷媒进口和冷媒出口，冷媒进口设置在热回收器的上部，冷媒出口设置在热回收器的下部，进水口开口于热回收器的上部，出水口开口于热回收器的下部。The heat recovery device is in the shape of a tank, and the heat exchange coil is coiled in the heat recovery device. The two ends of the heat exchange coil are respectively a refrigerant inlet and a refrigerant outlet. In the lower part of the recovery device, the water inlet is opened on the upper part of the heat recovery device, and the water outlet is opened on the lower part of the heat recovery device.
所述热回收器内还设置有用于测量水温的温度传感器，温度传感器与主控制器电连接。A temperature sensor for measuring water temperature is also arranged in the heat recovery device, and the temperature sensor is electrically connected with the main controller.
本实用新型由于回收利用了压缩机的高温排气的部分热量，对进入热回收器内的电热加湿器的低温供水进行预热，使其温度升高，从而减少该供水进入电热加湿器后，电热加湿器的电热元件对其再加热至汽化所需要能耗，以提高整个空调机的能效比。同时，由于压缩机排出的高温高压的冷媒在热回收器释放了能量，制冷系统的冷凝温度和冷凝压力有所降低，过冷度增大，制冷量有所上升，制冷压缩机的消耗功率也因此得以减小，故可进一步提高空调机的能效比。Because the utility model recycles and utilizes part of the heat of the high-temperature exhaust of the compressor, it preheats the low-temperature water supply of the electric heating humidifier entering the heat recovery device to increase its temperature, thereby reducing the water supply after entering the electric heating humidifier. The electric heating element of the electric humidifier needs energy consumption to reheat it to vaporization, so as to improve the energy efficiency ratio of the whole air conditioner. At the same time, because the high-temperature and high-pressure refrigerant discharged from the compressor releases energy in the heat recovery device, the condensing temperature and condensing pressure of the refrigeration system decrease, the degree of subcooling increases, the cooling capacity increases, and the power consumption of the refrigeration compressor decreases. Therefore, it can be reduced, so the energy efficiency ratio of the air conditioner can be further improved.
本实用新型中的热回收器可以对电热加湿器的进水进行预热处理，大幅度缩短电热加湿器对供水的升温汽化处理周期，提高了加湿速度，从而有效改善空调机的湿度控制精度和速度。The heat recovery device in the utility model can preheat the water intake of the electric humidifier, greatly shorten the heating and vaporization treatment cycle of the electric humidifier for the water supply, and increase the humidification speed, thereby effectively improving the humidity control accuracy of the air conditioner and speed.
本实用新型可广泛用于所有采用电热加湿器进行加湿的工艺性空调机，如恒温恒湿空调机、机房空调机和组合式空调机等。The utility model can be widely used in all technical air conditioners that use electric heating humidifiers for humidification, such as constant temperature and humidity air conditioners, machine room air conditioners and combined air conditioners.
