Temperature/humidity independently-treated clean air conditioning unit

Abstract

The invention discloses a temperature / humidity independently-treated clean air conditioning unit, which belongs to the technical field of refrigeration and air-conditioning equipment. The unit comprises a return air inlet, a supplied air outlet, an exhaust air outlet, a fresh air inlet, a return air primary filter, a return air fan, a return air regulating valve, a fresh air regulating valve, a fresh air primary filter, a fresh air treating coil, an air mixing box, a supplied air treating coil, a supplied air secondary filter and a supplied air fan. According to the invention, the technical scheme of connecting two stages of coils in series is adopted, namely, fresh air is individually treated by using an independent fresh air treating coil so as to undertake the indoor latent heat load; after fresh air and return air are mixed, the obtained air mixture is treated by using an independent supplied air treating coil so as to undertake the indoor sensible heat load, therefore, the unit can carry out free regulation on any sensible heat load and latent heat load, so that the waste of energy caused by reheating is effectively avoided; and the indoor comfortableness is improved. When the indoor calorific value is extremely high, the unit can still satisfy the indoor temperature / humidity treatment requirements, and has a better regulative property; and the unit can be applied to the field of high-calorific-value industrial cleaning.

Description

technical field [0001] The invention belongs to the technical field of refrigeration and air-conditioning equipment, in particular to a purification air-conditioning unit used for independent processing of temperature and humidity in an air-conditioning system. Background technique [0002] In order to improve the energy efficiency of the air conditioning system, the independent control of temperature and humidity has attracted more and more attention from the industry. The fresh air and indoor return air of this type of system are handled independently. The fresh air is mainly used to bear the latent heat load in the room, while the return air with high ventilation frequency is only used for cooling treatment and bears the sensible heat load in the room. energy consumption, and can provide a very comfortable and hygienic indoor environment. The successful development of purification air-conditioning units with independent treatment of temperature and humidity will promote ...
