Description
Technical field
The utility model relates to the air source hot pump water heater field, is the accurate two stages of compression screw compressor of having of a kind of good energy-conserving effect heat pump specifically.
Background technology
Screw compressor is that the refrigerating heat pump industry is used a kind of of compressor, and it has radial compliance and axial elasticity two specific characters.Allowing scroll plate to separate to a side thereby radial compliance can be guaranteed the scroll plate contact passes through and unlikely damage scroll plate impurity and liquid; Axial elasticity then can be kept constant, the uniform pressure in scroll plate tip and eliminate.Existing screw compressor has digital scroll compressor and two kinds of extension forms of air injection enthalpy-increasing compressor.
Digital scroll compressor has advantages such as quick conversion, the electric-control system adaptability simple, system that can realize the output capacity interval is strong.Yet, the shortcoming of digital scroll compressor is also fairly obvious, be that its operation is subjected to such environmental effects very big, particularly in the occasion of low temperature, because the compression volume of digital scroll compressor is less, performance impact mainly shows following two aspects under its low temperature environment: (1) heating capacity significantly successively decreases along with the decline of environment temperature, because the inspiratory capacity size is corresponding mutually with its air-breathing saturation temperature, along with environment temperature progressively descends, the heat pump evaporating temperature reduces, and the compressor air suction specific volume increases, and the gas transmission coefficient reduces, cause heating capacity to reduce the corresponding decline of heat pump Energy Efficiency Ratio.(2) parts operational reliability problem, especially compressor, under low temperature environment, evaporating temperature is crossed when hanging down, and the compression ratio of compressor increases and causes excessive discharge temperature, causes heat pump to occur back liquid easily, causes compressor damage when serious.
The air injection enthalpy-increasing compressor has good low temperature Energy Efficiency Ratio, and under the low-temperature working environment, heat pump still has heating performance preferably.But under high-temperature work environment, the overall work load of air injection enthalpy-increasing compressor is bigger, and capacity is higher during heat exchange, and compressor displacement is prone to overload operation, damages easily in its use.
Air injection enthalpy-increasing compressor and digital scroll compressor all can only use under specific use occasion at present, and it uses adaptability relatively poor, and can not take into account the various temperature environment.Therefore, existing screw compressor heat pump still awaits further improvement.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of good energy-conserving effect is provided, uses the adaptable accurate two stages of compression screw compressor heat pump that has.
Goal of the invention of the present utility model is achieved in that a kind of accurate two stages of compression screw compressor heat pump that has, it is characterized in that: described have accurate two stages of compression screw compressor heat pump and comprise screw compressor, condenser, throttling arrangement, processing making-up air device and the evaporimeter that is communicated with into closed circuit successively, screw compressor is provided with the working medium spray-hole, handle making-up air device and be communicated with the working medium spray-hole, condenser and evaporimeter are connected on the exhaust outlet and return-air mouth of screw compressor.
Be provided with magnetic valve between described condenser and the exhaust outlet, the other end of magnetic valve is connected between throttling arrangement and the evaporimeter.
Described have accurate two stages of compression screw compressor heat pump and be provided with capacity regulating device.
Described capacity regulating device comprises conditioning chamber that is communicated with exhaust chamber and the external magnetic valve that is located on the screw compressor, and an end of external magnetic valve is connected between evaporimeter and the return-air mouth, and the other end is communicated with the conditioning chamber outlet.
The utility model improves the screw compressor heat pump of prior art, and accurate two stages of compression device and capacity regulating device are set on existing screw compressor heat pump.Accurate two stages of compression device is a set handling making-up air device in the closed circuit of heat pump, and the working medium spray-hole is set on screw compressor, handles making-up air device and is communicated with the working medium spray-hole.By the characteristics separately of digital scroll compressor technology and air injection enthalpy-increasing Compressor Technology are organically combined, the adaptability that whole heat pump is used has significantly raising.Heat pump can be done to regulate automatically to its compression ratio, heating capacity according to the needs of environment for use, has improved usage ratio of equipment greatly.Capacity regulating device then is that conditioning chamber and external magnetic valve are set on screw compressor, conditioning chamber is communicated with exhaust chamber, regulate by the compression volume of capacity regulating device in the heat pump use, guaranteed the normal operation of whole heat pump, improved the stability of compressor operating.
