Air conditioning device with quick-switchable heat recovery mode

The utility model discloses an air conditioning device with quick-switchable heat recovery mode, which comprises a condensation and evaporation system, a refrigeration heat exchanger and a cooling heat exchanger, wherein the condensation and evaporation system comprises a compressor and a gas-liquid separator in ring connection through a pipeline in the middle. A four-way reversing valve is connected in series with a refrigerant medium pipeline under liquid state and one drain pipe of the four-way reversing valve is connected with a domestic hot water exchanger; and then the domestic hot water exchanger is connected to the liquid inlet of the four-way reversing valve. The four-way reversing valve is additionally arranged on a condensation tube, so that degradation in air-conditioning performance and damage on heat recovery device because heat recovery mode is not adopted in part of the heat recovery system of an air-conditioning system are avoided, and the heat recovery mode and non-heat recovery mode can be
