Problems solved by technology

[0002] The traditional heat pump air-conditioning system uses the method of simultaneous processing of air latent heat and sensible heat. In summer, it is necessary to reduce the temperature of the processed air to the dew point and then perform reheat compensation, resulting in high energy consumption of the energy-consuming system and surface coolers or evaporators. Mold is easy to grow on the surface; in winter conditions, it is impossible to humidify the room, resulting in poor thermal comfort
At the same time, traditional heat pump air conditioners are not suitable for high temperature and low humidity and low temperature and high humidity conditions in transitional seasons
[0003] Through the retrieval of the existing published technologies, it is found that the current heat pump air-conditioning system cannot be applied to the year-round working conditions and realize the independent treatment of sensible heat and latent heat at the same time
For example, the Chinese patent application number 20160428215.2 "Dehumidification air-conditioning system and air-conditioning control method" is equipped with two indoor heat exchangers and corresponding bypass circuits, so that the system can be applied to low-temperature and high-humidity environments, but it is still not applicable to year-round working conditions and there is no Independent treatment of sensible heat and latent heat
For example, the Chinese patent application number 200810200429.X "Ground source heat pump air conditioning system based on independent control of temperature and humidity" handles the latent heat load through the dehumidification wheel, and uses the cooling coil to handle the sensible heat load, but it is only suitable for high temperature and high humidity conditions
