Described auxiliary condenser B is near refrigerant main heat exchanger A, and auxiliary condenser D is near refrigerant main heat exchanger C, and auxiliary condenser also can be connected on common conducting strip with main heat exchanger.
In the course of work of the present invention, when main heat exchanger A does evaporimeter use, main heat exchanger C does condenser use, compression exchange system flows into refrigerant by commutation from main heat exchanger C one end, from flowing out, the main heat exchanger C other end connects No. four reversal valves, from the threeway bypass of No. four reversal valves, flow out, the threeway bypass of No. four reversal valves connects auxiliary condenser B, the threeway bypass of the port of export of auxiliary condenser B and No. three reversal valves is connected, wherein the tie point between No. three reversal valves and No. four reversal valves is in cut-off state, in another export pipeline of No. three reversal valves, be connected with expansion valve, filter, a reversal valve and No. two reversal valves, and then get back to compression exchange system after being connected with the main heat exchanger A using as evaporimeter, described auxiliary condenser B is near main heat exchanger A, auxiliary condenser B also can be connected on common conducting strip with main heat exchanger A.
When main heat exchanger C does evaporimeter use, main heat exchanger A does condenser use, compression exchange system flows into refrigerant by commutation from main heat exchanger A one end, from flowing out, the main heat exchanger A other end connects a reversal valve, from the threeway bypass of a reversal valve, flow out, the threeway bypass of a reversal valve connects auxiliary condenser D, the threeway bypass of the port of export of auxiliary condenser D and No. two reversal valves is connected, wherein the tie point between a reversal valve and No. two reversal valves is in cut-off state, in another export pipeline of No. two reversal valves, be connected with expansion valve, filter, No. three reversal valves and No. four reversal valves, and then get back to compression exchange system after being connected with the main heat exchanger C using as evaporimeter, described auxiliary condenser D is near main heat exchanger C, auxiliary condenser D also can be connected on common conducting strip with main heat exchanger C.
When the residing environment temperature of the main heat exchanger using as condenser rises, the high temperature refrigerant that flows out condenser is connected with auxiliary condenser by two reversal valves, and auxiliary condenser is arranged on by evaporimeter, and can to evaporimeter, provide heat by heat radiation, the high temperature refrigerant that makes to flow out condenser by evaporimeter forced refrigeration, becomes low temperature refrigerant by auxiliary condenser, and low temperature refrigerant evaporates after by throttling expansion in evaporimeter, to extraneous caloric receptivity, increase, improved efficiency.
