Abstract
The utility model provides a low temperature air source heat pump, which can generate heat normally even under low temperature outdoor environment conditions, and is provided with better economical and applicable effects. The heat pump is provided with a high temperature system and a low temperature system. In a low temperature environment (around-30 to -2 Celsius system), the two systems operate recursively: an evaporator (22)of the low temperature system absorbs the heat from the low temperature environment; refrigerants sends the heat to a condenser (17)of the low temperature system; the heat is transmitted from the condenser (17)of the low temperature system to an evaporator (14)of the high temperature system; and refrigerants in the high temperature system sends the heat to an heat exchanger (10)of the high temperature system. When the environment temperature is high, the high temperature system operates and the refrigeration and heat generation functions for common heat pumps can still be maintained. Double-system heat generation and single-system heat generation can be controlled to switch automatically through a solenoid valve according to the environment temperatures. The single-system refrigeration and heat generation can be switched by a four-way valve in a conventional way.

Summary of the invention:
The purpose of this utility model provides a kind of low-temperature air source heat pump.The air source heat pump that it has solved present made only is applicable to the southern area that the winter environment temperature is higher, the problem that can only use when weather is not too cold the lower northern area of environment temperature.
Low-temperature air source heat pump is (-30～-2 ℃ approximately) when environment temperature is low, adopt the mode of two-shipper overlapping to carry out heating operation, not only can normally heat work, and have better economic and practicality; When environment temperature is higher (approximately more than-2 ℃), the unit high-temperature systems is moved, and still preserves refrigeration, the heat-production functions of original common heat pump.
(1). when environment temperature is higher (more than 2 ℃), the operation of unit high-temperature systems is freezed, is heated with usual manner.
(2). when environment temperature is low (-30～-2 ℃ approximately), adopt the method for operation of two-shipper overlapping to heat.
(3). the two-shipper overlapping heats, unit heats, and switches with magnetic valve, automaticallyes switch and controls automatically according to environment temperature.Unit freezes, heats in the usual way and switch with cross valve.
(4). temperature (air-conditioning) compressor during the compressor in the system adopts; Warm cold-producing medium during cold-producing medium adopts.
(5). 10 heat exchangers can be air-cooled or water-cooled among Fig. 1.
The utility model has the advantages that:
1. when environment temperature is low (-30～-2 ℃ approximately),, 1. not only can normally heats work, and have better economic and practicality owing to adopt two-shipper overlapping mode to carry out heating operation.2.. reduced exhaust temperature, the temperature and pressure machine that contracts can normally move in can making.3. reduce compression ratio, improved operating efficiency, had higher economical efficiency and practicality.(if adopt cryogenic compressor, though compressor also can operate as normal, economy is too poor, does not have practical value).
2. unit is still preserved refrigeration, the heat-production functions of original conventional equipment; The two-shipper overlapping heats, unit heats according to environment temperature and changes automatically; Unit freezes, heats in the usual way and switch with cross valve.
