Double-cold source full fresh air dehumidifier and control method thereof

Abstract

The invention discloses a double-cold source full fresh air dehumidifier and a control method thereof. The problems that a full fresh air dehumidifier has high energy consumption, high-quality exhaust and low-temperature condensate water are not fully utilized, and air outlet temperature cannot be subjected to stepless regulation in a range from 16 to 24 DEG C are solved. The double-cold source full fresh air dehumidifier comprises a heat recovery device, a surface-cooling humidifying system, a direct-expansion humidifying system and a condensate water recovery system. The devices and systemsform a fresh air treatment functional section and an exhaust condensation functional section. Multi-dimensional energy-saving technologies such as double-cold source deep dehumidification, heat pipe energy conservation, condensation heat multi-point extraction, built-in evaporative condensation, exhaust and condensate water energy recovery and the like are comprehensively utilized, and the dehumidifier has the characteristics of simple and reasonable structure, high intelligent degree, low energy consumption, low manufacturing cost and flexible operation.

Description

technical field [0001] The invention relates to the technical field of dehumidifiers, in particular to a fresh air dehumidifier with dual cooling sources and a control method thereof. Background technique [0002] With its unique air treatment method and engineering adaptability, fresh air dehumidifiers have been widely used in various occasions that require fresh air dehumidification, such as national defense projects, medical and health fields, and warehouses for storing toxic and harmful substances. But we know that the fresh air dehumidifier has no return air, and all the fresh air with high heat and humidity outside is processed. Compared with the return air type dehumidifier, the fresh air dehumidifier usually consumes a lot of energy. In addition, the fresh air air conditioning system has indoor exhaust air, and the fresh air treatment process will be accompanied by continuous condensed water. Generally, the indoor exhaust air is directly discharged to the outside, an...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a new double cold source comprehensively utilizing multi-dimensional energy-saving technologies such as double cold source deep dehumidification, heat pipe energy saving, multi-point heat removal of condensation heat, built-in evaporative condensation, exhaust air and condensed water energy recovery. The air dehumidifier solves the problem that the fresh air dehumidifier itself has high energy consumption, does not make full use of high-quality exhaust air and low-temperature condensed water, and cannot realize the stepless adjustment of the outlet air temperature between 16-24°C
