Air conditioner, fresh air heat pump circulation pipeline thereof and heat recovery control system and method

Abstract

The invention discloses an air conditioner, a fresh air heat pump circulation pipeline thereof and a heat recovery control system and method. The fresh air heat pump circulation pipeline comprises a fresh air circulation assembly comprising a first fresh air passage, a second fresh air passage, an exhaust passage and a selector switch, and a heat pump circulation assembly, wherein when the selector switch is in a first operation state, the first fresh air passage is connected, and the second fresh air passage is disconnected; when the selector switch is in a second operation state, the first fresh air passage is disconnected, and the second fresh air passage is connected; the heat pump circulation assembly comprises a first evaporator arranged in the exhaust passage, a water storage tank and a condenser arranged in the water storage tank; and a refrigerant pipe of the first evaporator is connected into the water storage tank and connected with the condenser condenser in the water storage tank. In this way, the air conditioner with the fresh air heat pump circulation pipeline avoids waste of heat, and can provide domestic hot water for user at the same time, and the exhaust air heatrecovery efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioner, its fresh air heat pump circulation pipeline, and a heat recovery control system and method. Background technique [0002] During the working process of the air conditioner, the condenser of its outdoor unit will generate a large amount of heat, while in traditional household air conditioners, the heat from the condenser of the outdoor unit is generally discharged directly, and there is a lack of recovery and utilization devices for this part of the heat, resulting in energy waste. Especially in air conditioners with a fresh air system, no matter what the outdoor temperature is, the exhaust air of the fresh air system will be stable at 22-26°C, and this part of the exhaust air with a higher temperature is directly discharged to the outside, causing more serious of energy waste. Contents of the invention [0003] The technical problem to be solved b...
