Abstract
The invention relates to an air conditioning unit and particularly relates to an exhausting and heating heat pump air conditioning unit. The exhausting and heating heat pump air conditioning unit comprises a throttling valve, an air cooling heat exchanger, a shell pipe heat exchanger, a four-way reversing valve, a gas-liquid separator, a heating coiled pipe, an electric adjusting valve and a compressor, wherein the compressor, the four-way reversing valve and the gas-liquid separator are in sealed connection in sequence; and the air cooling heat exchanger, the throttling valve, the shell pipe heat exchanger and the four-way reversing valve are in sealed connection in sequence. The exhausting and heating heat pump air conditioning unit has the advantages that when liquid in the gas-liquid separator is too much, the compressor is used for exhausting and heating in a bypass manner, so as to prevent from a phenomenon that a liquid refrigerating agent is sucked into the compressor to cause liquid impact; the size of the gas-liquid separator is reduced, manufacturing materials are saved and the space is saved; and the exhausting and heating heat pump air conditioning unit is simple to mount and is easy to produce and operate.
Description
Technical field
The present invention relates to air-conditioner set, especially a kind of heating exhaust gas heat pump air conditioner unit.
Background technology
Existing air-cooled heat-pump air-conditioner group, heats in work in the winter time, and because outdoor environment temperature is low, heating capacity decay is very large, often can not meet the requirement of air conditioner heat load, and indoor air temperature in air conditioned building reduces, degree of comfort decreased.Now, air cool heat pump air conditioning system can increase the pressure of refrigerant system condenser, reduce the pressure of evaporimeter, need cold-producing medium than many during refrigeration when whole refrigeration system is heated, when working conditions change, have and do not have the liquid refrigerant evaporated get back to compressor and compressed, due to the incompressible characteristic of liquid, will " liquid hammer " fault of compressor be caused.In order to prevent " liquid hammer ", present air cool heat pump air conditioning system, at the gas-liquid separator that compressor air suction mouth installation volume is larger, this improper increase cost, and take up space.
Summary of the invention
The object of the invention is to overcome defect of the prior art, adopt a kind of heating exhaust gas heat pump air conditioner unit, when liquid is too much in gas-liquid separator, exhaust bypass is heated, prevent liquid refrigerant to be inhaled into compressor and cause liquid hammer, install simple, be easy to operation.
For achieving the above object, technical scheme of the present invention adopts a kind of heating exhaust gas heat pump air conditioner unit, comprise choke valve, air cooling heat exchanger, case tube heat exchanger, four-way change-over valve, gas-liquid separator, heat(ing) coil, electric control valve, compressor, described compressor, four-way change-over valve, gas-liquid separator are closed successively and are connected, and described air cooling heat exchanger, choke valve, case tube heat exchanger, four-way change-over valve are closed successively and connected.
One end of described electric control valve connects compressor exhaust pipe, is connected on the air intake duct of compressor after the other end connection heat(ing) coil of described electric control valve.
Described heat(ing) coil is arranged on the inside of gas-liquid separator, and the air inlet pipe of described gas-liquid separator is arranged on bottom, and the escape pipe of described gas-liquid separator is arranged on top.
Beneficial effect of the present invention is:
(1), when liquid is too much in gas-liquid separator, exhaust bypass is heated, prevents liquid refrigerant to be inhaled into compressor and cause liquid hammer.
(2) reduce the size of gas-liquid separator, save the material manufactured, save space.
(3) install simply, be easy to production operation.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
In figure: choke valve 1, air cooling heat exchanger 2, case tube heat exchanger 3, four-way change-over valve 4, gas-liquid separator 5, heat(ing) coil 6, electric control valve 7, compressor 8.
Detailed description of the invention
Composition graphs 1 pair of specific embodiment of the invention is further described:
According to technical scheme provided by the invention, a kind of heating exhaust gas heat pump air conditioner unit, comprise choke valve 1, air cooling heat exchanger 2, case tube heat exchanger 3, four-way change-over valve 4, gas-liquid separator 5, heat(ing) coil 6, electric control valve 7, compressor 8, described compressor 8, four-way change-over valve 4, gas-liquid separator 5 are closed successively and are connected, and described air cooling heat exchanger 2, choke valve 1, case tube heat exchanger 3, four-way change-over valve 4 are closed successively and connected.
One end of described electric control valve 7 connects compressor 8 blast pipe, is connected on the air intake duct of compressor 8 after the other end connection heat(ing) coil 6 of described electric control valve 7.
Described heat(ing) coil 6 is arranged on the inside of gas-liquid separator 5, and the air inlet pipe of described gas-liquid separator 5 is arranged on bottom, and the escape pipe of described gas-liquid separator 5 is arranged on top.
The course of work of the present invention is: after using the present invention, when the liquid refrigerant flowing to gas-liquid separator 5 is many, regulate the aperture of electric control valve 7, the exhaust of compressor 8 enters gas-liquid separator 5, heating liquid, the liquid of gas-liquid separator 5 is evaporated, and the gas-liquid mixture of coming from case tube heat exchanger 3 enters from the bottom of gas-liquid separator 5, the air-breathing of compressor 8 sucks steam from the top of gas-liquid separator 5, prevents liquid hammer.
The advantage of the present embodiment is, when in gas-liquid separator 5, liquid is too much, liquid by heating evaporation, will prevent liquid refrigerant to be inhaled into compressor 8 and cause liquid hammer; Reduce the size of gas-liquid separator 5, save the material manufactured, save space; Install simple, be easy to production operation.
