Air handling device with natural heating and humidity control

Abstract

An air handling device with natural heating and humidity control comprises a compressor, an air-cooled heat exchanger, a water-cooled heat exchanger, a reheater, a three-way valve, a throttle device, a valve and a humidifier. The air handling device is characterized in that switching between steam compression refrigerating circulation and natural heating circulation can be realized via the three-way valve, and the air handling device can realize various thermal processes including cooling dehumidifying, constant-humidify cooling, constant-humidify warming, warming humidifying and the like. In other words, the air handling device can realize cool supply and dehumidifying in summer and transitional seasons, can meet requirements of warming by means of natural heating in winter, and then saves energy effectively. Further, the air handling device is additionally equipped with a refrigerant pump, thereby increasing running property and reliability of a natural circulation mode and simultaneously eliminating position and height limitation between the air-cooled heat exchanger and the water-cooled heat exchanger. Moreover, the air handling device is adaptable to an industrial air conditioning system required to be used for cooling and dehumidifying in summer and warming and humidifying in winter in the Northern area and a comfortable air conditioning system having severe requirements on temperature and humidity.

Description

technical field [0001] The invention relates to an air treatment device with natural heating and humidity control, which is suitable for industrial air-conditioning systems that require cooling and dehumidification in summer and heating and humidification in winter, and is also suitable for comfort air-conditioning that requires stricter temperature and humidity requirements. The system belongs to the field of refrigeration and air-conditioning equipment. Background technique [0002] In my country's current industrial energy consumption, the air conditioning system occupies a large proportion. The high energy consumption of the air conditioning system increases the production cost on the one hand, and more importantly, the high energy consumption puts a huge pressure on the energy system. In today's increasingly tense energy situation, this problem becomes more serious. [0003] Different production processes determine the different heat and humidity load characteristics a...

Problems solved by technology

In order to ensure that the air supply parameters are within the required range, there is a common problem of reheating after cooling and dehumidification. At present, steam reheating and electric heating reheating methods are mostly used. These methods have the phenomenon of cold and heat offsetting, which wastes both cooling and heat. serious waste of energy

[0004] At present, the temperature-adjusting dehumidifiers used in industrial places can basically meet the cooling and dehumidifying needs in summer, but there are some problems in winter heating: 1) When the outdoor temperature is low in winter, the evaporation temperature of the vapor compression heat pump cycle is low , The compression ratio is relatively large, and the outdoor unit needs to be defrosted and defrosted, which makes the system performance poor and the heatin
