Description
Technical field
The utility model relates to air-conditioning technical field, specifically, relates to a kind of heat recovery module formula air-cooled unit.
Background technology
Along with the raising of socioeconomic development and people's living standard, the application of air-conditioning is more and more universal.Such as the region such as public place and large supermarket generally uses central air-conditioning, central air-conditioning technology obtains in China and applies widely, Central air-conditioning unit generally comprises compressor, evaporimeter, throttling arrangement and condenser, and condenser can produce used heat when air conditioner refrigerating runs, go if the used heat of condenser is directly discharged in air, not only waste thermal source, but also can to environment.Therefore, current people are also trying to explore the heat recovery technology of air-conditioning condenser.
At present, Waste Heat Recovery for the condenser in air cooling module generally takes two kinds of modes, the first is connected heat recovering heat exchanger between compressor and air-cooled condenser, the recuperation of heat mode of this structure, because air-cooled condenser setting height(from bottom) is much larger than the setting height(from bottom) of heat recovering heat exchanger, when heat exchanger works, the refrigerant gas of the high pressure-temperature that compressor is discharged, undergo phase transition after heat recovering heat exchanger, refrigerant liquid is had to condense out, cold-producing medium becomes gas-liquid mixture, cold-producing medium overall flow speed is diminished, liquid part in cold-producing medium is difficult to be passed in air-cooled condenser, cause easy hydrops in heat exchanger.It two is that heat exchanger is in parallel with air-cooled condenser, and by the flow direction of triple valve or cross valve conversion cold-producing medium, when heat recovery function is enabled, triple valve is energized, refrigerant flow direction heat recovering heat exchanger and do not flow to air-cooled condenser; Otherwise cold-producing medium flows to air-cooled condenser, and do not flow to heat recovering heat exchanger.This mode in use, due to the conversion of triple valve, easily causes the instability that refrigerant system runs.
Utility model content
Technical problem to be solved in the utility model is: provide the heat recovery module formula air-cooled unit that a kind of refrigerant system is stable, can prevent hydrops in heat recovering heat exchanger.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of heat recovery module formula air-cooled unit, the evaporimeter comprising compressor, the air-cooled condenser be connected with described compressor outlet and be connected with the entrance point of described compressor, throttling arrangement is connected with between described air-cooled condenser and described evaporimeter, be in series with heat recovering heat exchanger between described air-cooled condenser and described throttling arrangement, the setting height(from bottom) of described heat recovering heat exchanger is lower than the setting height(from bottom) of described air-cooled condenser.
Preferably, also reservoir is connected with between described heat recovering heat exchanger and described throttling arrangement.
Preferably, described throttling arrangement is expansion valve.
After have employed technique scheme, the beneficial effects of the utility model are:
Heat recovery module formula air-cooled unit of the present utility model, is in series with heat recovering heat exchanger between air-cooled condenser and described throttling arrangement, and the setting height(from bottom) of described heat recovering heat exchanger is lower than the setting height(from bottom) of described air-cooled condenser.The heat recovery module formula air-cooled unit of this structure in use, from compressor discharge refrigerant high pressure high-temperature gas after air-cooled condenser heat exchange, form refrigerant air-liquid mixture, because the setting height(from bottom) of heat recovering heat exchanger is lower than the setting height(from bottom) of air-cooled condenser, refrigerant air-liquid mixture flows to heat recovering heat exchanger from air-cooled condenser is top-down, refrigerant air-liquid mixture is under the double action of pressure itself and gravity, flow velocity compare the effect only having pressure itself when want fast, efficiently avoid in system the problem producing hydrops.And in the utility model, heat recovering heat exchanger is connected in systems in which, be not parallel connection in systems in which, make the cold-producing medium in system stable.Multiple-way valve need not be adopted to change back and forth, avoid and use multiple-way valve to change the systematic jitters caused back and forth.

Detailed description of the invention
Fig. 1 is the systematic schematic diagram of heat recovery module formula air-cooled unit of the present utility model.
With reference to Fig. 1, a kind of heat recovery module formula air-cooled unit, the evaporimeter 6 comprising compressor 1, the air-cooled condenser 2 be connected with compressor 1 port of export and be connected with the entrance point of compressor 1, be connected with throttling arrangement between air-cooled condenser 2 and evaporimeter 6, the throttling arrangement in the present embodiment adopts expansion valve 5.Be in series with heat recovering heat exchanger 3 between air-cooled condenser 2 and expansion valve 5, the setting height(from bottom) of heat recovering heat exchanger 3 is lower than the setting height(from bottom) of air-cooled condenser 2.Heat recovering heat exchanger 3 is connected to hot water inlet pipe 31 and hot water outlet pipe 32, the refrigerant air-liquid mixture that band has surplus heat enters the refrigerant circulation pipe heat recovering heat exchanger 3 from air-cooled condenser 2, the hot water to be added flow to from hot water inlet pipe 31 in heating heat recovering heat exchanger 3, after hot water heating to be added, hot water is discharged stand-by from the hot water outlet pipe 32 of heat recovering heat exchanger 3.
Reservoir 4 is also connected with between heat recovering heat exchanger 3 and expansion valve 5.In the present embodiment, reservoir 4 adopts stainless steel fluid reservoir.
Heat recovery module formula air-cooled unit of the present utility model, is in series with heat recovering heat exchanger 3 between air-cooled condenser 2 and expansion valve 5, the setting height(from bottom) of heat recovering heat exchanger 3 is lower than the setting height(from bottom) of air-cooled condenser 2.The heat recovery module formula air-cooled unit of this structure in use, from compressor 1 discharge refrigerant high pressure high-temperature gas after air-cooled condenser 2 heat exchange, form refrigerant air-liquid mixture, because the setting height(from bottom) of heat recovering heat exchanger 3 is lower than the setting height(from bottom) of air-cooled condenser 2, refrigerant air-liquid mixture flows to heat recovering heat exchanger 3 from air-cooled condenser 2 is top-down, refrigerant air-liquid mixture is under the double action of pressure itself and gravity, flow velocity compare the effect only having pressure itself when want fast, efficiently avoid in system the problem producing hydrops.And in the utility model, heat recovering heat exchanger 3 is connected in systems in which, be not parallel connection in systems in which, make the cold-producing medium in system stable, multiple-way valve need not be adopted to change back and forth, avoid use multiple-way valve change the systematic jitters caused back and forth.
