Description

Technical Field

[0001] The invention relates to the technical field of controllers, and in particular to an ultra-low temperature air energy heat pump controller. Background Art

[0002] Ultra-low temperature air energy heat pump is a device that uses the heat in the air to achieve heating. It can operate effectively even in low temperature environments (usually working normally at -25℃ or even lower). Its basic principle is based on the reverse Carnot cycle. The compressor compresses the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant enters the condenser, where it releases heat to the heated medium (such as water or air), and the refrigerant condenses into a high-pressure liquid. The liquid refrigerant is throttled and depressurized by the expansion valve, becoming a low-temperature and low-pressure liquid, and then absorbs heat from the air in the evaporator and vaporizes into a low-temperature and low-pressure gaseous refrigerant, and the cycle continues. Ultra-low temperature air energy heat pumps are used in home heating and cooling, commercial heating and hot water supply, and heat recovery and utilization in the industrial field. The ultra-low temperature air energy heat pump controller is a key component of the ultra-low temperature air energy heat pump system, which can accurately control the operating temperature of the heat pump. In heating mode, when the ambient temperature is low (such as in cold winter), the controller will adjust the operating frequency of the heat pump compressor and the fan speed and other parameters according to the set water outlet temperature or indoor temperature requirements. For example, when the user sets the indoor temperature to 20°C, the controller will monitor the data fed back by the indoor temperature sensor. Once the indoor temperature is lower than the set value, the heat pump will be started until the target temperature is reached. In the cooling mode, the cooling process will also be controlled according to the set temperature.
