| Zusammenfassung: | The utility model discloses a multi-mode total heat recovery type ground source heat pump air conditioning system. The multi-mode total heat recovery type ground source heat pump air conditioning system comprises a refrigerant main circulation loop, a one-way valve pipeline and a bypass pipeline. The refrigerant main circulation loop comprises a compressor, a four-way reversing valve, a user side heat exchanger and a buried side heat exchanger which are connected in series, and two throttling elements are connected in series in a throttling pipeline between the user side heat exchanger and the buried side heat exchanger; the one-way valve pipeline is connected with the throttling pipeline in parallel and is internally connected with two one-way valves in series; one end of the bypass pipeline is communicated with the exhaust end of the compressor, and the other end of the bypass pipeline is connected between the two throttling elements and the two one-way valves; the multi-mode total heat recovery type ground |
