The even following demand heated, and have both cooling in summer function.But the system is haveed the shortcomings that obvious, is still had very big
Improve and optimizate space: such as structure is complicated for major loop for system heating (or refrigeration), and pipe fitting is more, at high cost, system running resistance
Greatly, energy consumption is high, and COP is low；System uses heating power expansion valve to control using the temperature difference of delivery temperature and condensation temperature as target component
When air compensation, air compensation is insufficient in the lower situation of delivery temperature, and system COP is not achieved most preferably；System is removed using inverse circulation
Frost will lead to room temperature and acutely decline, and need to compensate the heat that defrosting absorbs again after restoring heating, room temperature fluctuates ratio
It is larger, comfort is poor etc..
Summary of the invention
In response to the problems existing in the prior art, the purpose of the present invention is to provide one kind, and refrigerating function is had both based on heating
Vortex type air source heat pump system.
A kind of the technical solution adopted by the present invention to solve the technical problems: whirlpool having both refrigerating function based on heating
Rotating air source heat pump system, it is passed by four-way reversing valve B, check valve F, solenoid valve C, high-voltage switch gear B, solenoid valve D, row's temperature

B, low tension switch B, water side shell and tube exchanger B, gas-liquid separator B, check valve H, device for drying and filtering B, fluid reservoir B, solenoid valve
F, the part such as piping filter, electric expansion valve B, economizer B, electric expansion valve C forms.1, system design is based on by jet
The air injection enthalpy-increasing systems technology that enthalpy-increasing compressor, air injection enthalpy-increasing technology and efficient subcooler are constituted.2, main loop base
The design concept of same electric expansion valve is shared in refrigeration, heating, by removing major loop solenoid, optimizes pipeline structure,
It is further reduced pipeline assembly.3, system tonifying Qi circuit uses electric expansion valve for restricting element, is control with the tonifying Qi degree of superheat
Target.4, system defrosting uses hot-gas bypass mode.When entering defrosting program, system still keeps heating working cycles, compression
The high-temperature gas of machine discharge is directly bypassed to air side fins heat exchanger, without condenser, not out of recirculated water and room
Heat absorption, input power of the defrosting energy mainly from compressor.5, in the defrosting stage of hot gas bypass defrosting, refrigerant is in sky
Releasing latent heat is undergone phase transition when being higher than 5 DEG C in the finned heat exchanger of gas side.Refrigerant liquid after defrosting enters gas-liquid separation
Device, partially liq flash into saturated gas under the swabbing action of compressor.Due in this multistage compressor suction superheat
0 DEG C or so is maintained always, compressor exhaust temperature is caused constantly to reduce, and jeopardizes the safe operation of compressor.Work as system detection
When being lower than set temperature to compressor exhaust temperature, the bypass solenoid valve being connected between compressor suction duct and exhaust pipe is timely
It opens, so that high-temperature gas is entered gas-liquid separator and increasing enthalpy processing is carried out to air-breathing, to maintain compressor exhaust temperature stable and protect
The refrigerant gasification that card enters compressor is abundant.
Beneficial effects of the present invention: 1, system reduces pipe fitting number by optimizing to heating (or refrigeration) main loop design
Amount, reduces running resistance, and system full working scope refrigerating capacity and COP is made to promote 3% or more.2, system is used with the tonifying Qi degree of superheat
To control target, the tonifying Qi technology of electric expansion valve is matched, the most stable and efficient, refrigerating capacity is averagely higher than to arrange
The gas degree of superheat is to control the system 8% of target, higher than the system 15% for taking delivery temperature as control target.3, system is using heat
The defrosting of gas bypass mode, not from condenser, recirculated water takes heat during defrosting, can restore heat supply at once after restoring heating；Room
Between temperature fluctuation very little, comfort is preferable；System defrosting during and switching when, pressure change is steady, caused by mechanical shock
It is smaller.4, hot gas bypass defrosting system has supplied short slab, can effectively avoid compressor liquid hammer by increase bypass solenoid valve,
Perfect system function.
