First time heat exchange is completed in the condenser outer circulation coil pipe 33 coupled in condenser 23 and condenser between circulating coil 231；Water
Source heat pump 2 does work, and will complete to pass to evaporator after the expanded valve 24 of exothermic low temperature heat-conducting medium is depressured in condenser 23
21, and completed second in evaporator 21 by circulating coil 211 in the evaporator of coupling and evaporator outer circulation coil pipe 13
Heat exchange, the heat-conducting medium after heat absorption heating back flow back into the heat release again of condenser 23 after the pressurization of compressor 23, form heat pump
Refrigeration cycle.Recirculated water after 13 heat exchange heat release of evaporator outer circulation coil pipe cooling is passed through circulating pump by output device 3
32 are transported to the heat in the absorption greenhouse of groundbed coil pipe group 31, and the heat release again of Returning evaporimeter 21 after heating forms output device 3
Refrigeration cycle.Heat in greenhouse in air is taken away by the absorption of groundbed coil pipe 313, reaches cooling effect in greenhouse.
Switched by the flexible heat supply of whole system and cooling condition, guarantees that the temperature in greenhouse maintains one always
Determine in range, is finally reached the effect of long-term constant temperature in greenhouse.
