Heat moisture segmental processing air-conditioning unit device and its air-treatment method

Abstract

The air treatment method of the air conditioning unit is divided into two parts, among which: the air treatment method of the heat and humidity section treatment is: after the indoor return air is mixed with the fresh air, it first passes through the first surface cooler (3) and high-temperature chilled water Heat exchange, cooling down to the dew point temperature after isohumidity, removing most of the sensible heat load, and then entering the second surface cooler (4); Condensed water is generated to remove the humidity load; the air after cooling and dehumidification is processed to the air supply state by the heater (5) and humidifier (6), and finally sent to the air-conditioned room after being pressurized by the fan (7); The method adopted is: the refrigerant in the first chiller unit enters the condenser (12) to condense after being compressed and discharged by the first compressor (11), and then passes through the first liquid storage tank (13) and the first filter (14) After being throttled and depressurized by the first electronic expansion valve (15), it enters the first evaporator (10) to exchange heat with chilled water.

Description

technical field [0001] The invention relates to an air treatment method for segmental treatment of air-conditioning loads and a device for realizing the method, and belongs to the technical field of design and manufacture of refrigeration and air-conditioning systems. Background technique [0002] The air conditioning load can be divided into sensible heat load and humidity load (latent heat load). The humidity load treatment methods in the air treatment process mainly include cooling and dehumidification, solution dehumidification, adsorption dehumidification, etc. Restricted by various factors, cooling and dehumidification is still the most commonly used method to deal with the humidity load of air conditioners. [0003] The method of cooling and dehumidification is to use cold water at a lower temperature to perform one-time cooling and dehumidification treatment on the air, and process it to the required saturation state, and then heat the air to the air supply state by ...
