Description
Technical field
The present invention relates to a kind of injection incremental type heat pump type air conditioning system and operational approach thereof, belong to air-conditioning and refrigeration technology field.
Background technology
Current vapor compression heat pump is air conditioning unit can be divided into according to condensing mode that water cooling heat pump is air conditioning unit, air-cooled heat-pump air-conditioner
Group and geo-source heat-pump air conditioner group.Wherein, water cooling heat pump is air conditioning unit is that logical supercooled water realizes heat exchange in condenser, but should
Systematic comparison is complicated, needs extra increase water pump and cooling tower blood circulation, adds equipment cost, improve initial cost, simultaneously
Equipment is arranged and is also subject to certain restrictions.Air-cooled heat-pump air-conditioner group uses forced ventilation mode to realize condenser inner refrigerant and air
Heat exchange, it is when summer, outdoor environment temperature was higher, and heat exchange effect is poor, be easily caused system condensing pressure and condensation temperature
Spend higher, thus affect the overall performance of refrigeration system;When winter heating, especially when ambient outdoor air humidity is bigger, steam
Send out the easy frosting of device heat exchange surface, thus reduce the time that effectively heats of unit, reduce the overall heating performance of system.Source, ground

Geographical conditions etc. limit, and need substantial amounts of pipe laying space.
From the point of view of current situation and long-range its development, air-cooled heat-pump air-conditioner group still has the biggest development potentiality.But existing wind
Cold evaporating condensation type heat exchanger, due to the refrigerant flow relative deficiency of channel interior, heat exchange area fails to be fully utilized,
Its heat transfer effect need to improve further.
For this technical problem, the evaporating condensation type water chiller-heater unit of patent CN201520339702.2 by using injector,
Can be to vaporizer (or evaporative condenser) feed flow under cooling in summer operating mode (or winter heating's operating mode).By cold-producing medium injection
Recirculation, increases evaporation side entrance refrigerant flow, reduces the mass dryness fraction of biphase gas and liquid flow, improve the coefficient of heat transfer of vaporizer.
But, this patented technology, because realize the reducing pressure by regulating flow process of system refrigerant only with injector, is configured without throttling accordingly
Valve, thus can not control and regulate the flow of system circulating refrigerant, thus it is dynamic to heat pump air conditioner sub-load to be difficult in adapt to user
The demand of regulation.
From the above analysis, the refrigerant flow in heat exchanger can be increased although with injector, thus improve changing of heat exchanger
Hot property.But owing to injector self does not possess the ability of regulated fluid flow, it is difficult to adapt to user and the regulation of sub-load is wanted
Ask, suddenly treat further to improve.
