Novel solution regulating-humidity fresh air handling unit with heat recovery function

Abstract

The invention relates to a novel solution regulating-humidity fresh air handling unit with the heat recovery function. The novel solution regulating-humidity fresh air handling unit with the heat recovery function comprises a solution module, refrigerating systems, a total heat recovery unit and a humidification module; the solution module comprises a regeneration solution module body and a dehumidifying solution module body which are connected through a pipeline; the refrigerating systems include the refrigerating system I and the refrigerating system II; the refrigerating system I comprisesa compressor I, a condenser I, an expansion valve I and an evaporator I which are connected annularly in sequence; the refrigerating system II comprises a compressor II, a water-plate heat exchanger,a condenser II, an expansion valve II and an evaporator II which are connected annularly in sequence; the total heat recovery unit comprises a cross-flow total heat exchanger; the humidification module is a water humidification module; the cross-flow total heat exchanger, the evaporator I, the evaporator II and the dehumidifying solution module body sequentially form an air inlet channel; and thecross-flow total heat exchanger, the condenser I, the regeneration solution module body, the water humidification module and the condenser II sequentially form an exhausting channel. The novel solution regulating-humidity fresh air handling unit with the heat recovery function is simple in structure.

Description

technical field [0001] The invention relates to a solution-type air treatment device, in particular to a novel solution humidity-conditioning fresh air unit with heat recovery. Background technique [0002] Humans spend at least 70% of their time indoors, but the concentration of indoor air pollutants is generally 2-5 times that of outdoor pollutants, and in some cases dozens or even hundreds of times that of outdoor pollutants. These pollutants are triggers for respiratory diseases, lung cancer, asthma, and more. Indoor pollution has become an invisible killer lurking around people. [0003] At present, the fresh air units on the market only have the functions of filtering PM2.5 and heat exchange, and do not have the functions of sterilization and dehumidification (humidification). Moreover, electrostatic sterilization will generate ozone, reduce indoor air quality, and have low accuracy in controlling indoor temperature and humidity. [0004] Among the existing solution ...

Problems solved by technology

[0003] At present, the fresh air units on the market only have the functions of filtering PM2.5 and heat exchange, and do not have the functions of sterilization and dehumidification (humidification). Moreover, electrostatic sterilization will generate ozone, reduce indoor air quality, and have low accuracy in indoor temperature and humidity control.

[0004] Among the existing solution humidity control air conditioners, the heat pump solution humidity control air conditioner has a relatively mature technology and a wide range of applications. However, the heat pump solution humidity control air conditioner has a complex structure, high cost, and large volume, and has high requirements for the machine room. Installation is not flexible enough for small space construction projects
