Technical field
The novel three alliance machine set systems that relate to a kind of air source heat pump of this reality, particularly a kind of machine set system that can in ultralow temperature, carry out air-source three combined supply heat pumps of work under the environment.
Background technology
Now the three alliances system of answering of collection refrigeration, heating, hot water is used for heat hot water for reclaiming used heat summer during running refrigerating, improves refrigeration efficiency and obtains free hot water; Winter, the operating heat pump pattern was used for a multi-functional unit of heating and heat hot water.
The energy-saving effect of three alliance units is very obvious, the double effects that the electric weight of input refrigeration can be freezed and heat, Energy Efficiency Ratio is up to 5.0-7.0, but three present alliance units all are to correct one's mistakes on common air conditioner heat pump system basis, unit in the area of severe cold owing to the scope of application restriction of compressor, system can not normally move and operational energy efficiency than the reason such as too low, can not satisfy the severe cold area demand that heats in winter, still to fill Secondary Heat Source in the winter time, so greatly affect the promoted extension of three alliance units.
Summary of the invention
Effective use of answering for air conditioner and heat pump unit three alliances of realizing severe cold area, reduce use cost, improve practicality and the usability of product, the utility model provides a kind of ultra-low temperature air source heat pump three alliance machine set systems, system comprises water cooling heat exchanger, water-cooled condenser, compressor, cross valve, air cooling heat exchanger, expansion valve one, fluid reservoir, connect respectively water cooling heat exchanger by cross valve, water-cooled condenser, compressor, air cooling heat exchanger, expansion valve one, fluid reservoir consists of, it is characterized in that: described compressor is to adopt the low-temperature air injection enthalpy increasing compressor, described water cooling heat exchanger, be provided with in addition economizer between the compressor, capillary connects, and forms tonifying Qi and increases the enthalpy loop.
Described fluid reservoir is provided with check valve and controls.
Described economizer is provided with magnetic valve one in addition, expansion valve two is controlled.
Described capillary is provided with in addition magnetic valve two and controls.
After adopting said structure, refrigerant is by opening magnetic valve one and expansion valve two enters economizer, heat absorption flashes to gas, enter the press intermediate cavity by gas supplementing opening, improve the press capacity, increase the press input power, reduce compression ratio, improve the stability that system moves under low temperature environment, opened magnetic valve two at delivery temperature Gao Shike and carry out capillary system is carried out fluid infusion, reduced rapidly delivery temperature, when can be implemented in-25 ℃, this system can also run well, and having realized is needing the severe cold area of heating, can effectively the using of air-conditioning heat pump three alliance units.
