Abstract

The invention relates to an air-conditioning unit device by heat-moisture subsection treatment and an air treating method thereof. The air treating method is divided into two parts, wherein, the air treating method of heat-moisture subsection treatment comprises that: indoor return air and fresh air are mixed, exchange heat with high-temperature cooling water through a first surface air cooler (3) first, reduces to the dew-point temperature through constant wetness, removes most of sensible heat load and enters to a second surface air cooler (4); in the second surface air cooler (4), air and low-temperature cooling water further exchange heat, are cooled, generate condensed water and remove the sensible heat load; the air after temperature reduction and dehumidification is treated to an air feeding state point by a heater (5) and a humidifier (6), finally pressurized by a blower (7) and sent to an air-conditioning room; the air-conditioning unit device adopts the following method that: refrigerant in a first water chiller unit is compressed and discharged by a first compressor (11) and enters a condenser (12) for condensation, then passes through a first liquid storage tank (13) and a first filter (14), is throttled and depressurized by a first electronic expansion valve (15) and enters a first evaporator (10) for heat exchange with cooling 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 ...
