Technical field
The utility model belongs to the cold and hot energy transporting technical field, relates to a kind of with a kind of reducing energy consumption scheme that adds the heat-pipe refrigerating system in the cold and hot pump refrigeration system of original list and carry out.
Background technology
The air-conditioning system that is used for the regulation and control environment temperature at present mainly consists of indoor heat exchanger and outdoor heat exchanger, this air-conditioning system can realize the temperature adjusting to condensing agent by the highly energy-consuming of compressor in the indoor heat exchanger, thereby indirect change indoor environment temperature, this air-conditioning system is not accomplished good energy savings, when outdoor temperature is lower than indoor temperature, because (extraneous dust concentration is big for certain reason, air pollution etc.) can not open window and carry out direct cross-ventilation cooling, the compressor of at this moment also having to open highly energy-consuming carries out adjustment, this phenomenon is at the dustproof environment (machine room of high temperature, special high temperature occasions such as electricity chamber) performance is obvious especially, because the use occasion heat dissipation equipment is concentrated, heat dissipation capacity is big, the space temperature height, quick heating, prevent dust and require high characteristic, making uses traditional air-conditioning to be difficult to conserve energy here, start the heat pump cooling even also have to when outdoor temperature is more much lower than indoor temperature, and the more energy-conservation brand-new wind of a kind of introducing carries out temperature reduction way a lot of areas is inapplicable at home now, a large amount of outdoor dust and humid air can be brought into indoorly, the safety that influences indoor equipment is normally moved.
The form of the another kind of wind that adopts---wind heat exchanger can be avoided introducing outdoor dust and humid air indoor, but need offer bigger ventilation hole at safeguard structures such as equipment room, machine room enclosure walls, not only destroy the stability of body of wall, also have stolen potential safety hazard.
Some season throughout the year, as winter and spring and autumn, lower and can not carry out under the situation of indoor-outdoor air convection current than the design temperature in indoor heat release zone in outdoor temperature, the compressor that did not also have a kind of system can need not open highly energy-consuming in this case in the past just can carry out indoor temperature control, even in this case, the compressor that existing air-conditioning system must start highly energy-consuming particularly those caloric values is concentrated temperature is controlled to environment in the demanding workplace of cleannes, this scheme that still adopts heat pump to lower the temperature to cool off is not energy-conservation, thereby the unnecessary waste that causes electric energy, operation costs are high.
According to this situation, a kind of new energy-conservation hybrid system has appearred again, the patent No. is 2012203709247, this kind scheme is that pipe of energy-saving heat system and forced cooling heat pump are combined, automatically open suitable pattern at the appropriate time, when being lower than indoor temperature, outdoor temperature can not only utilize outdoor temperature to use the cooling of the indirect property of heat pipe pattern like this, directly lower the temperature but also can when indoor temperature is lower than outdoor temperature, open heat pump mode, this mode has improved energy-saving efficiency completely, but this is faced with new problem again, the appearance of new energy-conserving product must make large quantities of old products more replace, have a lot of heat pump refrigerating system not arrive and eliminate the time limit, cause very big waste, and a lot of base station machine room is cooperating the heat pump cooling installation to build to form especially, so just cause bigger quantities, more cost waste.
