Now, working medium flow is: the first valve (V1), the second valve (V2), the first expansion valve (Vt1), the second expansion valve (Vt2) Open；Working substance steam is divided into two-way from compressor (COM) outlet: a road enters the 3rd heat exchanger (HE III), at the 3rd heat exchanger Entering working medium tank (T) after cooling is condensed into liquid in (HE III), liquid refrigerant is further divided into two-way after working medium tank (T) flows out, a road warp First Heat Exchanger (HE I) is entered, in First Heat Exchanger (HE I) and from solar energy heating after crossing the second expansion valve (Vt2) blood pressure lowering The ethylene glycol solution heat exchange evaporation of device (SC), generates low-temp low-pressure working substance steam, and another road is after the first expansion valve (Vt1) blood pressure lowering Access the second heat exchanger (HE II), and in the second heat exchanger (HE II) with the ethylene glycol solution heat exchange from closed cooling tower (CCT) Evaporation, generates low-temp low-pressure working substance steam, accesses the driving fluid entrance of ejector (EJE)；Separate from compressor (COM) outlet Another road working medium access the Working-fluid intaking of ejector (EJE) through the first valve (V1), injection is from the second heat exchanger (HE II) Low-temp low-pressure working substance steam, two-way working medium mix in ejector after from ejector outlet flow out, change with from first the most again The working substance steam of hot device (HE I) is converged, is entered compressor (COM) recompression, so circulates；

Low-temperature glycol solution flow process is: a mouth of the 4th valve (V4) and b mouth, the e mouth of the 5th valve (V5) and h mouth, Seven valves (V7), the 8th valve (V8) are opened, and the 6th valve (V6), the 9th valve (V9), the tenth valve (V10) are closed, and second Solvent pump (P_L2) ethylene glycol solution absorbing outdoor low-temperature air energy in closed cooling tower is passed through a mouth of the 4th valve (V4) Send in the second heat exchanger (HE II) with b mouth, return to enclosed by the h mouth of the 5th valve (V5) and e mouth after heat release cooling cold But in tower；

Middle temperature ethylene glycol solution flow process is: the 3rd valve (V3), the c mouth of the 4th valve (V4) and d mouth, the 5th valve (V5) F mouth and g mouth open；First solvent pump (P_L1) ethylene glycol solution is sent into heat absorption in the 3rd heat exchanger (HE III) to heat up, afterwards Return to user's end (UE) heat；

High temperature glycol solution flow process is: the 11st valve (V11), the 12nd valve (V12) are opened, the 13rd valve (V13), 14th valve (V14) is closed；The high temperature glycol solution flowed out by solar thermal collector (SC) enters First Heat Exchanger (HE I), Solar thermal collector (SC) is returned after heat release cooling.

Application the most according to claim 5, it is characterised in that under cooling condition, compressor (COM) and ejector (EJE) During combined running, low-temperature glycol solution flow process is cascade: the b mouth of the 4th valve (V4) and c mouth, the 5th valve (V5) G mouth and h mouth, the 6th valve (V6), the 8th valve (V8), the tenth valve (V10) open, the 7th valve (V7), the 9th valve Door (V9) is closed, and the ethylene glycol solution after user's end (UE) heat absorption is by the first solvent pump (P_L1) by the b mouth of the 4th valve (V4) Send into First Heat Exchanger (HE I) with c mouth, after working medium absorbing and cooling temperature, enter the second heat exchanger (HE II) by the tenth valve (V10) Cooling, returns to user's end (UE) through the 8th valve (V8), the h mouth of the 5th valve (V5) and g mouth afterwards further；

Or parallel form: the b mouth of the 4th valve (V4) and c mouth, the g mouth of the 5th valve (V5) and h mouth, the 6th valve (V6), the 7th Valve (V7), the 8th valve (V8), the 9th valve (V9) are opened, and the tenth valve (V10) is closed, after user's end (UE) heat absorption Ethylene glycol solution is through the first solvent pump (P_L1) being divided into two-way: a road enters First Heat Exchanger (HE I) heat release cooling, another road enters Second heat exchanger (HE II) heat release is lowered the temperature, after the low-temperature glycol solution after two-way cooling converges, by the h of the 5th valve (V5) Mouth and g mouth return user's end (UE).
