A dual cold source dehumidification fresh air machine

Abstract

The invention discloses a double-cold-source dehumidification fresh air ventilator. The double-cold-source dehumidification fresh air ventilator structurally comprises a fan box, an air return system,an air exhaust system, a fresh air system, an air supply system, a control panel, a self-updating deionized water humidifier, a cooling device and a filter device, wherein the fan box is of a rectangular structure, the air return system is arranged on the front upper part of the fan box, the air exhaust system is arranged on the back upper part of the fan box, the fresh air system is arranged onthe back lower part of the fan box, and the air supply system is arranged on the front lower part of the fan box. According to the double-cold-source dehumidification fresh air ventilator, the self-updating deionized water humidifier is arranged, so that the defect of inapplicability in dry autumn and winter because the humidifying function of the equipment is bad is improved, the problems of peculiar smell and bacteria caused by manual water adding and wet membrane humidification in a traditional technique are solved, condensate water generated during dehumidification is collected and is stored in a self-updating water tank after being deionized, the latest water can be collected, the older water can be automatically replaced, the humidifying water without smell or bacteria is guaranteed,and the quality of fresh air is increased.

Description

technical field [0001] The invention relates to the field of air-conditioning compressors, more precisely, it relates to a dehumidifying fresh fan with double cooling sources. Background technique [0002] In the HVAC system, supplying fresh air to the room in time is an indispensable part to ensure human health. Ordinary fresh air units are generally composed of fans and surface cooling coils. As the end of air treatment, the unit cools down the room and at the same time precipitates moisture in the air to achieve the purpose of dehumidification. However, the dual cooling source dehumidification fresh air machine of the prior art has the following defects: [0003] In autumn and winter when the air is relatively dry, a certain degree of humidification is required while supplementing fresh air. However, humidification is a shortcoming. It can only be humidified externally, and water needs to be added manually. Since the humidification function is only used in autumn and win...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a dual cooling source dehumidification fresh air machine to solve the problem that in the prior art dual cold source dehumidification fresh air machine, in autumn and winter when the air is relatively dry, a certain degree of fresh air needs to be supplemented at the same time. Humidification treatment, but humidification is its shortcoming. It can only be humidified externally, and water needs to be added manually. Since the humidification function is only used in autumn and winter, adding ordinary water will often produce odor and breed bacteria due to long storage time. , or use wet film to humidify, but the wet film is a breeding ground for bacteria and microorganisms, which will also pollute the air.
