Abstract
The utility model discloses a constant-temperature constant-humidity direct-current frequency-conversion double-stage heat recovery air conditioner. Refrigerating fluid inside a gas-liquid separator flows to a compressor, an oil separator, a fin condenser and a fin evaporator sequentially, and flows back to the gas-liquid separator, so that a refrigerant circulation loop is manufactured. A refrigerant fluid discharge end of the fin condenser is further sequentially connected with a check valve, a reheating condenser and a heat recovery energy-regulation valve, and the refrigerant fluid discharged by the energy-regulation valve flows back to the fin condenser. Due to the adoption of the structural style and due to the fact that an electric heating pipe is replaced by the reheating condenser, waste heat is recovered and utilized, and consumption of electrical energy is greatly reduced. In addition, due to the addition of a plate-type aqueous medium heat exchanger, after heat transfer is conducted on high-temperature high-pressure refrigerant fluid output by the compressor, water flowing out of the plate-type aqueous medium heat exchanger becomes hot water, and therefore the constant-temperature constant-humidity direct-current frequency-conversion double-stage heat recovery air conditioner not only provides hot water for daily life, but also alleviates burden of a condensing fan.
