Description

Air-conditioning equipment

The utility model relates to a kind of air-conditioning equipment, particularly relates to a kind of air-conditioning equipment that is provided with heat reclaim unit, and it can reclaim heat, energy savings.

Along with the raising of living standards of the people, much more more and more air-conditioner has also come into family.As durable consumer goods, aspect power consumption, air-conditioner and other household electrical appliance are compared as refrigerator, washing machine, television set etc., the power consumption of air-conditioner is considerably beyond the summation of other household electrical appliance power consumption, sometimes even reach more than 90% of the whole power consumption of family.Because China is populous, energy owning amount is significantly less than the mean level of developed country per capita.Under the situation of China's energy wretched insufficiency, how to reduce power consumption, become the major subjects of current air-conditioning professional research.

According to law of conservation of energy, the air-conditioner running must power consumption.So, should consider to make full use of this energy.

Accompanying drawing 1 is the composition structural representation of existing domestic air conditioner.The operation principle of this domestic air conditioner is: compressor sucks the superheated steam of the low pressure refrigerant after evaporimeter heat absorption vaporization, through being collapsed into the refrigerant vapour of HTHP, goes into air-cooled condenser side by side.Because blower fan continuously makes outdoor air flow through condenser, cool off, and make the superheated steam that flows through the high-pressure refrigerant in the condenser tube be condensed into liquid.Behind this high pressure refrigerant liquid process device for drying and filtering, when flowing through capillary,, simultaneously its temperature is further reduced, and become the refrigerant liquid of low-temp low-pressure by the throttling step-down.Then, be sent to evaporimeter heat absorption boiling, thereby just cooled off the room air of the evaporimeter of under fan action, flowing through, also just reached the refrigeration purpose.Cold-producing medium after the heat absorption vaporization enters compressor, finishes a kind of refrigeration cycle.

Condenser is absolutely necessary as a part of air-conditioning system complete cycle, does not have condenser just can not freeze.If the heat exchange area of condenser or heat exchange amount are too little, refrigerating capacity does not just reach designing requirement.

The purpose of this utility model is to solve above-mentioned problems of the prior art, and a kind of air-conditioning equipment with heat reclaim unit is provided, and it can make full use of the heat energy that produces in the air conditioner, produces another kind of thermal medium by thermal power transfer.

In order to achieve the above object, the utility model provides a kind of air-conditioning equipment, it comprises evaporimeter, compressor and condenser, wherein evaporimeter and compressor interconnect by compressor suction duct, be provided with heat reclaim unit between compressor and condenser, the refrigerant outlet in the described compressor is communicated with refrigerant inlet in the heat reclaim unit, and the refrigerant outlet in the heat reclaim unit is communicated with refrigerant inlet in the condenser.

In the air-conditioning equipment that the utility model provides, refrigerant outlet in the described compressor is communicated with refrigerant inlet in the heat reclaim unit by downtake pipe, and the refrigerant outlet in the described heat reclaim unit is communicated with refrigerant inlet in the condenser by second exhaust pipe.

In the air-conditioning equipment that the utility model provides, described heat reclaim unit comprises the pipeline of housing, conducting cold-producing medium, and heat exchange media channel.

In the air-conditioning equipment that the utility model provides, the entry and exit of the heat exchange media channel in the described heat reclaim unit are connected with storage tank by outlet pipe and feed pipe respectively.

In the air-conditioning equipment that the utility model provides, in described storage tank, water supply control valve is set, between storage tank and feed pipe, be provided with water pump.

Adopt this air-conditioning equipment, can reach 150 ℃ through the superheated refrigerant vapor (steam) temperature that produces after the compressor compresses, be introduced into liquid suction heat exchanger, it is the heat retracting device, through after the water cooling, enter the air-cooled type heat exchanger cooling again, through getting back to compressor again after the evaporimeter refrigeration, form a kind of refrigeration cycle then.

Water in the elevated tank after the cooled dose of heating, because of water temperature difference, produces power through the bottom of bottom pipe nature inflow heat exchanger, and hot water is upwards flowed, and gets back to elevated tank by water pipe, forms the Natural Circulation of heat exchange medium.Along with the air-conditioning equipment growth of running time, water temperature is more and more higher, up near 100 ℃.

Adopt in the process that this air-conditioning equipment freezes, under the situation that consumes the as much electric weight, both reached the refrigeration purpose, the hot water of having got back, thus saved the energy.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
