For achieving the above object, the technical solution used in the present invention is a kind of environment-friendly type solution air-cooling type heat pump air conditioning group, comprise compressor, be connected to the refrigerant reversal valve at compressor, also be connected to cold-producing medium-solution heat exchanger and cold-producing medium-air heat exchanger on the refrigerant reversal valve, cold-producing medium-solution heat exchanger is by the check valve group, liquid reservoir, filter and expansion valve and cold-producing medium-air heat exchanger join, on cold-producing medium-solution heat exchanger, also be connected to respectively interconnective solution pump and solution-air heat-exchange core body, also be connected on solution-air heat-exchange core body except the aqueous solution-air caloic exchange core body, be connected to respectively on except the aqueous solution-air caloic exchange core body interconnective except water-circulating pump with except water heater.
The other air circulation fans that is provided with of described cold-producing medium-air heat exchanger.
The other heat exchange blower fan that is provided with of described solution-air heat-exchange core body.
Described except the aqueous solution-other being provided with except Water fan of air caloic exchange core body.
Described solution-air heat-exchange core body and except connecting by balance pipe between the aqueous solution-air caloic exchange core body.
Also be provided with liquid level sensor on the described aqueous solution-air caloic exchange core body.
Compressor connects the refrigerant reversal valve when heating, under the effect of refrigerant reversal valve and check valve group, refrigerant condensation in cold-producing medium-air heat exchanger realizes the intensification to circulated air, simultaneously refrigerant cold evaporation in cold-producing medium-solution heat exchanger, solution are emitted and are flow through solution-air heat-exchange core body behind the heat under the effect of solution pump and absorb heat, Water Cycle work to outdoor air; Solution is being heated except flowing through the heater that dewaters under the effect of water-circulating pump, flows through except the aqueous solution-air caloic exchanges core body and discharges the moisture periodic duty to air; The effect of balance pipe is the liquid level of each solution tank solution of balance unit and passes through each solution tank solution concentration of molecular diffusion balance; The start and stop of liquid level sensor control solution de-watering apparatus.
Operation principle is:
The high temperature and high pressure gas that compressor is discharged during heating condition enters through the refrigerant reversal valve that cold-producing medium-air heat exchanger is flow through cold-producing medium-air heat exchanger air cooling and condensation becomes subcooled liquid, enters cold-producing medium-solution heat exchanger again behind liquid reservoir, expansion valve reducing pressure by regulating flow, absorption is flow through and is become superheated steam behind the heat of cold-producing medium-solution heat exchanger solution and be inhaled in the compressor, thereby finishes the circulation of coolant system; Solution is emitted and is flow through solution-air heat-exchange core body behind the heat under the effect of solution pump and absorb heat, Water Cycle work to outdoor air; Solution is being heated except flowing through the heater that dewaters under the effect of water-circulating pump, flows through except the aqueous solution-air caloic exchanges core body and discharges the moisture periodic duty to air, and balance pipe balancing machine solution level also passes through molecular diffusion balance solution concentration; The start and stop of liquid level sensor control solution de-watering apparatus.
Beneficial effect: the present invention adopts the solution de-watering apparatus to keep unit internal solution amount, prevents that on the one hand liquid level from raising and overflow and cause environmental pollution; Keep on the other hand solution concentration and guarantee that the normal operation of unit need not to add solute.
