Small household-type solution humidifying fresh air handling unit for external cold source

Abstract

The invention relates to a small household-type solution humidifying fresh air handling unit for an external cold source. The small household-type solution humidifying fresh air handling unit mainly comprises an auxiliary cold source, a refrigerating system and a solution module. The auxiliary cold source conducts precooling and pre-dehumidification on fresh air with cooling capacity provided by external high-temperature cold water. An evaporator of the refrigerating system conducts further cooling and dehumidification on the fresh air with cold capacity provided by the refrigerating system of the unit. The heat and humidity transfer mode of gas-liquid crossflow is adopted in a heat and humidity transfer core of the solution module. The refrigerating system includes one or more compressors, the evaporator, a condenser and one or more expansion valves. An outlet of the evaporator is connected with inlets of the compressors, and outlets of the compressors are connected to an inlet of the condenser. An outlet of the condenser is connected to inlets of the expansion valves, and outlets of the expansion valves are connected to an inlet of the evaporator. Therefore, a heat pump refrigerating system circulation loop can be formed.

Description

Technical field [0001] The invention relates to a solution type air treatment device, in particular to a small household type solution humidity adjustment fresh air unit with an external cold source, belonging to the field of solution humidity adjustment air conditioning, in particular to the field of solution type air treatment devices. 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 tens or even hundreds of times that of outdoor pollutants. These pollutants are the cause of respiratory diseases, lung cancer, asthma and other diseases. Indoor pollution has become an invisible killer lurking around people. [0003] At present, the fresh air unit on the market only has the function of filtering PM2.5 and heat exchange, and does not have the functions of sterilization and dehumidification. Moreover, electrostatic sterilization will genera...

Problems solved by technology

[0005] Among the existing solution humidity control air conditioners, the heat pump solution humidity control air conditioner has a relatively mature technology and a wide application range. However, the heat pump solution humidity control air conditioner unit 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
