Description
Technical field
The utility model relates to the Teat pump boiler field of components, is the processing making-up air device of a kind of multipurpose heat pump system specifically.
Background technology
Screw compressor is applied to air-conditioner, Teat pump boiler production and manufacturing just gradually as the rotation-positive displacement compressor of a kind of compression efficiency height, good energy-conserving effect.But in the air-conditioner of configuration screw compressor, the heat pump, screw compressor have that pressure of inspiration(Pi) is less, delivery temperature is higher and low temperature environment under the characteristic of poor-performing, above-mentioned characteristic causes bigger influence to the use of Teat pump boiler, and the most outstanding shortcoming is exactly that the scope of application restriction of air-conditioner, Teat pump boiler is bigger.The heat pump of configuration screw compressor in use, along with environment temperature progressively descends, the heat pump evaporating temperature reduces, the compressor air suction specific volume increases, the gas transmission coefficient reduces, and causes heating capacity to reduce the corresponding decline of heat pump Energy Efficiency Ratio.In addition, under low temperature environment, evaporating temperature is crossed when hanging down, and the compression ratio increase of compressor can cause excessive discharge temperature, causes heat pump to occur back liquid easily, can make compressor damage when serious.Therefore, the structure of multipurpose heat pump system still awaits further improvement.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and strengthen multipurpose heat pump system equipment reliability, improves the processing making-up air device that heat pump uses adaptive multipurpose heat pump system.
Goal of the invention of the present utility model is achieved in that the processing making-up air device of a kind of multipurpose heat pump system, comprise the inlet pipe, indoor heat exchanger communicating pipe and the outdoor heat exchanger communicating pipe that are communicated with heat exchanger, it is characterized in that: described inlet pipe, indoor heat exchanger communicating pipe and outdoor heat exchanger communicating pipe are communicated with gas-liquid separation device through throttling arrangement A, throttling arrangement B and throttling arrangement C respectively.
Described gas-liquid separation device is provided with the blowdown pipe that is communicated with the compressor return air section.
Described blowdown pipe is provided with magnetic valve.
Described gas-liquid separation device is four hole flash vessels.
Described throttling arrangement B is an electric expansion valve.
Described throttling arrangement C is an electric expansion valve.
Described throttling arrangement A is made up of capillary, check valve, magnetic valve.
The utility model improves the multipurpose heat pump system of prior art, between three kinds of heat exchangers gas-liquid separation device is set, and the throttling arrangement that series connection with it is communicated with is set on gas-liquid separation device.Gas-liquid separation device is provided with the blowdown pipe that is communicated with the return-air section of compressor, and magnetic valve is set on blowdown pipe.By the control of gas-liquid separation device, throttling arrangement and magnetic valve, gas working medium can be returned after gas-liquid separation device is finished dealing be sprayed onto compressor return air circular flow, effectively reduce the influence of low temperature environment to heat pump work.And making-up air device is set in the return-air section of compressor, and can make the inspiratory volume of compressor and gas transmission specific volume keep stable, ensured the heating capacity of heat pump.
