High-low-temperature double-cold-source dual-system air conditioning system based on fresh air low-temperature deep dehumidification

Abstract

The invention discloses a high-low-temperature double-cold-source dual-system air conditioning system based on fresh air low-temperature deep dehumidification. The system comprises a temperature and humidity independent control and ultra-large temperature difference water or ice cold storage air conditioning system and a temperature and humidity independent adjustment system based on fresh air deep dehumidification, wherein the temperature and humidity independent control and ultra-large temperature difference water or ice cold storage air conditioning system comprises an air ventilation system water supply and return unit, a low-temperature plate heat exchanger is connected to a water outlet of the air ventilation system water supply and return unit through a pipeline, a water outlet of the low-temperature plate heat exchanger is connected with a three-way pipe, and one end of the three-way pipe is connected with a cold storage pool through a pipeline. According to the system, the temperature and humidity independent control and ultra-large temperature difference water cold storage air conditioning system is involved, when an air ventilation system of an air conditioner is used, the air ventilation system directly adopts chilled water at the temperature of 5-12 DEG C for efficient deep dehumidification, the air quality is comprehensively improved, the temperature can be accurately controlled, the humidity can also be accurately controlled, and the air comfort level is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning fresh air and systems, and in particular relates to a high-low temperature dual-cooling source dual-system air-conditioning system based on fresh air low-temperature deep dehumidification. Background technique [0002] According to the characteristics of the air conditioning system that mainly needs to adjust the two parameters of temperature and humidity, it only needs to dehumidify the outdoor fresh air until it is dry enough to take away the indoor humidity load, and supply the indoor fan with high-temperature chilled water at a relatively high temperature of 14-19 °C The coil can easily adjust the indoor temperature and humidity. There are also solution dehumidification units and dual-temperature cold source dehumidification units for fresh air system dehumidification, but these two dehumidification units have a common problem: large volume and large space occupation. Each machine ne...
