Ventilation and refrigeration equipment and its control method

Abstract

The invention provides a ventilation and refrigeration device and its control method. The ventilation and refrigeration device can be set on a wearable device; it includes: a thermoelectric module, a first heat dissipation module and a second heat dissipation module; and a gas pollutant sensor and an air purification module. The pollutant sensor can detect the concentration of air pollutants in the space on the side of the wearable device facing the human body in real time; the air purification module can purify the air on the side of the wearable device facing the human body, and the air purification module can also detect air pollutants according to the gas pollutant sensor. The concentration of air pollutants can be reminded whether it should be turned on, or turned off or replaced. According to the present invention, the problem that the inside temperature of the wearable device (preferably a mask) will be relatively high after wearing, and whether the air purification filter material needs to be replaced cannot be automatically judged inside the mask can not only reduce the inside temperature, but also effectively judge the air purification Whether the filter material needs to be replaced, the degree of intelligence is effectively improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a ventilation refrigeration device and a control method thereof. Background technique [0002] As a sanitary product, a mask is generally worn on the nose and mouth to filter the air entering the nose and mouth, so as to block harmful gases, odors, droplets, viruses and other substances. [0003] Under normal circumstances, masks are only used by specific groups of people or under special environmental conditions. The wearing time is relatively short, and the wearing comfort has not attracted people's attention. Masks have a certain filtering effect on the air entering the lungs. It has a very good effect when respiratory infectious diseases are prevalent, and when working in a polluted environment such as dust. However, in hot summer or in a poorly ventilated room, wearing a mask is stuffy and hot. In addition to increased discomfort, skin diseases may even occur. Howeve...

Problems solved by technology

[0006] Therefore, the technical problem to be solved by the present invention is mainly to overcome the defects that the inside temperature of the mask in the prior art is relatively high after wearing, and it is impossible to automatically judge whether the air purification filter material needs to be replaced in the mask, thereby providing a ventilation and cooling Device and its control method
