Description
Technical field
The present invention relates to heat and kind of refrigeration cycle technical field, more particularly to a kind of double source low-temperature enthalpy-increasing heat pump.
Background technology
Heat pump is increasingly subject to pay attention to as a kind of energy saver, and is considered as the effective means of energy-saving and emission-reduction.Heat pump
System can provide refrigeration due to summer, and winter can provide heat, and be widely used because its is easy to operate.But
Xia Redong cold area, because winter outdoor temperature is relatively low, compression ratio is big and frosting problem prevent air source heat pump from by
Widely use, therefore just seem very for searching out a kind of senior source pump that can be used in the season of hot-summer and cold-winter area two
It is necessary.In sum, in order to solve the shortcoming for being difficult to rapid popularization that air source heat pump exists in actual applications, that is, compress
Than big, heat with freeze it is dual-purpose be difficult to, and evaporimeter frosting and efficiency run low technical problem, it is necessary to existing heat
Pump is further transformed and upgraded.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of simple structure, working stability and can realize
Winter frost removing and summer are using compressor second vapor injection and the double source low-temperature enthalpy-increasing heat pump of internal heat energy-conservation.
To achieve the above object, technical scheme provided by the present invention is：A kind of double source low-temperature enthalpy-increasing heat pump, including compression
Machine, it is characterised in that：Also include the heat exchanger that blast pipe, qi leel tank, four-way valve and a pair of series are connected, wherein the exhaust
Pipe one end is connected with the compressor, and its other end is connected with the qi leel canister incoming gas mouthful；Described point of its gas outlet of gas tank is also
It is connected with the compressor by the connecting tube being provided with, for air injection enthalpy-increasing in the compressor, wherein the four-way
Valve is arranged on the blast pipe, and the four-way valve is arranged between the connected heat exchanger of a pair of series, the exhaust
High-voltage switch gear is also respectively provided with pipe and increasing enthalpy connecting tube；Also it is connected in series between the connected heat exchanger of a pair of series
Second throttling device and heat exchanger.
Further, also it is correspondingly arranged on respectively for exhaust probe and air-breathing probe installation in the blast pipe and connecting tube
Exhaust probe socket and air-breathing probe socket.
Further, an increasing enthalpy connecting tube being arranged between the qi leel tank and blast pipe, the wherein increasing are also included
Two-way electromagnetic valve and first throttle device are provided with enthalpy connecting tube.
Further, the heat exchanger is also equipped with blower fan thereon.
Preferably, the two-way electromagnetic valve is to be entered by the suction temperature of its outside environment temperature or the compressor
Row controls its action.
Compared with prior art, this programme has the beneficial effect that：By controlling the port mode of communicating of four-way valve, system is realized
The normal operation being switched fast with various heat exchangers under two kinds of working conditions of cold and supplying thermal condition；This programme is by profit simultaneously
Switched with the commutation of the four-way valve, when realizing that heat supply in the winter time and cooling in summer run, compressor is all with the operation of air injection enthalpy-increasing
Mode operation, reaches the purpose for providing systematic function；In addition this programme crosses cold heat exchanger using four-way reversing valve and refrigerant,
Winter heats the air of the air-cooled heat exchanger of the first refrigerant by being used as evaporator, prevents the first refrigerant air-cooled
Heat exchange frosting；Stop the use that refrigerant crosses cold heat exchanger in summer, it is to avoid energy flows back.
