The invention discloses a temperature control dehumidification system and a temperature control dehumidification method for the fresh air of a radiation air conditioner. The system comprises an air duct system, a radiation water circulation system and a cooling system, wherein the air duct system comprises a fresh return air treatment air duct and an exhaust air heat recovery air duct, which are independent; a pre-cooler / pre-heater and a temperature control heat exchanger are integrated corrugated finned type internally-threaded coiled pipes, and are connected with a radiation water inlet / outlet pipeline to form the radiation water circulation system; one stage of evaporator is used for direct evaporation, and two stages of condensers are connected in parallel to form a double-stage condensation cooling compression system. The system can be combined with the radiation air conditioner to independently control temperature and humidity, and besides a conditioning treatment function of a conventional dehumidification system, the system also has an exhaust air heat recovery function; a household compression cooling air conditioner is combined with the dehumidification system to realize cooling in summer, heating in winter and humidification in transition seasons; the running energy consumption is greatly lowered, and the shortcomings of dehumidification incapability and high condensation rate of the radiation air conditioner are overcome.
Description
technical field [0001] The invention relates to a multifunctional fresh air temperature control dehumidification system for a household type radiant air conditioner and a year-round temperature control dehumidification method for the fresh air temperature control dehumidification system. Background technique [0002] The radiant air-conditioning system originated in Europe and is a new type of air-conditioning system that has developed rapidly in my country in recent years. Radiant cooling and heating technology has the advantages of energy saving, shifting peak power consumption, improving grid efficiency, comfortable indoor environment and saving building space. However, the radiant air-conditioning system itself does not have the dehumidification ability. When the radiant surface temperature is lower than the air dew point temperature, condensation will occur, which will affect the indoor sanitary conditions and use, especially in the Yangtze River Basin of China. This ph...
