Description

technical field

[0001] The invention relates to a heat pump air conditioner and water heater, in particular to a heat pump air conditioner and water heater suitable for efficient operation in a wide temperature environment. Background technique

[0002] Compared with water source heat pump air conditioners and ground source heat pump air conditioners, air source heat pump air conditioners have the characteristics of simple structure and convenient configuration. Compared with the electric heating tube water heater, the heat pump water heater has the characteristics of low energy consumption and high efficiency. However, the current air-source heat pump air conditioners and air-source heat pump water heaters have poor heating effects in low-temperature environments below 0°C, and their heating energy efficiency ratio decreases significantly with the decrease of ambient temperature, especially when the ambient temperature is close to - At 5°C, if the auxiliary electric heatin...
