The connection of described first and second two-position four-way valves 9,8 is identical with connection of the prior art.Wherein, the outlet end 3c of condenser 3 outlet sides links to each other with the first interface 8a of second two-position four-way valve 8, and its liquid feeding end 3d links to each other with the first interface 9a of first two-position four-way valve 9; The feed tube 11 of air-conditioner links to each other with the second interface 8b of second two-position four-way valve 8, the liquid back pipe 11 ' of air-conditioner links to each other with the 4th interface 9d of first two-position four-way valve 9, shown in the drain pipe 1b of evaporimeter 1 input side link to each other with the 3rd interface 8c of described second two-position four-way valve 8, its feed tube 1a links to each other with the 3rd interface 9c of first two-position four-way valve 9; The liquid back pipe 12b of described accumulator 200 links to each other with the 4th interface 8d of second two-position four-way valve 8, and the drain pipe 12a of described accumulator 200 links to each other with the second interface 9b of first two-position four-way valve 9 with pump 50.In heat exchange loop, be filled with working medias such as water or anti-icing fluid.
The course of work of the present invention is:
In the time of in the winter time, heat energy enters the energy lift device 300 through the Pump for giving-out (not shown) from the drain pipe 12a of accumulator 200, sends into the input of evaporimeter 1 through first two-position four-way valve 9.In evaporimeter 1, carry out heat exchange, with the outlet side of heat transferred evaporimeter 1.Liquid after heat exchange is through drain pipe 1b, second two-position four-way valve 8, flows back to accumulator 200.Meanwhile, the working medium R22 in the evaporimeter 1 is admitted in the compressor 2, becomes high temperature and high pressure gas and is sent to condenser 3 through the compression of at least two compressors 2.In condenser 3, the high temperature and high pressure gas of sending by compressor 2 with condenser 3 mutually the working media of coupling carry out heat exchange, after the heat exchange, heated liquid-working-medium is through drain pipe 3c, by the water heater and second two-position four-way valve 8, and the feed tube 11 inflow air-conditioners of air-conditioner heat up to room air.Liquid-working-medium after the air-conditioner heat radiation is by liquid back pipe 11 ', the first two-position four-way valve 9 of air-conditioner, and liquid feeding end 3d flows back in the condenser 3, the circulation of finishing the work.
Winter indoor heating, accumulator 200 must provide enough Lowlevel thermal energies.Because the heat transfer rate of soil is very slow, it is difficult reaching continuous reliability service.Strengthening the temperature difference and utilizing phase transformation potential is a comparatively effectively way.Strengthen the heat transfer rate that the temperature difference can improve soil.Utilize the phase transformation of water in the time of 0 ℃ just can absorb a large amount of latent heat, the heat that provides like this is just comparatively sufficient and reliable.Problem is owing to absorb the purpose that the temperature of Lowlevel thermal energy can not reach heating.If connect a compressor again behind compressor, the high temperature of compressor can satisfy the requirement of heating like this.Therefore the present invention needs at least two compressors in the winter time during heating.
During summer, the course of work of native system is opposite with winter, first two-position four-way valve and the commutation of second two-position four-way valve.Cryogenic liquid enters the energy lift device 300 through Pump for giving-out 50 from the drain pipe 12a of accumulator 200, sends into the outlet side of condenser 3 through first two-position four-way valve 9.In condenser 3, carry out heat exchange, the heat of absorptive condenser 3 input sides.Liquid after heat exchange is through drain pipe 3c, second two-position four-way valve 8, flows back to accumulator 200.Meanwhile, the working medium R22 in the condenser 3 sends in the evaporimeter 1 by expansion valve 4, carries out the heat exchange heat absorption after compressor 2 (open by-passing valve 13 this moment, uses a compressor) flows back in the condenser 3 in evaporimeter 1.The working medium of input side flow to the input 11 of air-conditioner through its outlet end 1b, second two-position four-way valve 8 in evaporimeter 1, carries out room conditioning and regulates cooling.The liquid back pipe 11 ' of air-conditioner flows back in the input side of evaporimeter 1 by first two-position four-way valve 9.The circulation of finishing the work.
Summer, the room will obtain coldly just must absorbing cold and heat being discharged to the earth from the earth.Finish the quantity that this mission just needs to increase accumulator if depend merely on accumulator, so very uneconomical, furthermore land occupation is more also unrealistic.Therefore the present invention is provided with heat extraction cover 6 above accumulator 200, and hot gas is discharged from heat extraction cover air flue, constantly replenishes air from air intake duct, quickens the heat exchange of accumulator, so just can accomplish the continuous operation of refrigeration in summer.
