Air handling device used for machinery room

Abstract

The invention relates to an air handling device used for a machinery room, comprising a box body; the box body is internally provided with an indoor side air-circulating fan and an outdoor side air-circulating fan; the box body is provided with an indoor side air inlet, an indoor side air outlet, an outdoor side air inlet and an outdoor side air outlet; the box body is internally provided with a first heat exchanger used for heat exchange of indoor and outdoor air and a second heat exchanger used for heat exchanging of indoor air and cycle fluid; the indoor air exchanges heat with the outdoor air flowing through an outdoor side air channel of the first heat exchanger from an indoor side air channel of the first heat exchanger; the indoor air exchanges heat with the cycle fluid flowing through the second heat exchanger from the indoor side air channel of the second heat exchanger; and the air channel of the indoor side air flowing through the first heat exchanger is arranged in parallel or series with the air channel of the indoor side air flowing through the second heat exchanger. The air handling device has the characteristics of heat exchanging temperature-reducing function and cooling temperature-reducing function with outdoor air; the indoor air cycle adopts the same fan; and the arrangement and installation are flexible and convenient.

Description

technical field [0001] The invention relates to an air treatment device, in particular to an air treatment device for a machine room. Background technique [0002] In industrial production, there are often some equipment that needs to be operated all the year round, and these equipments emit heat during operation, and there is a cooling load throughout the year that requires air treatment. The air treatment device for the computer room disclosed in the present invention is proposed to solve this problem. [0003] Taking the telecommunications base station as an example, since the base station has waste heat dissipated during operation, it needs to cool the air throughout the year. Currently, there are three commonly used cooling methods. The first way is to cool down through the base station air conditioner. The base station split air conditioner has the same settings as the room comfort split air conditioner. The indoor unit includes an indoor heat exchanger and throttling ...

Problems solved by technology

Generally, the power of the compressor of the air conditioner is very large, especially for the situation where the outdoor temperature is low, although its energy efficiency has increased, but it consumes a lot of electricity, which is not conducive to energy saving and emission reduction.

[0004] The second method is to use filtered fresh air to blow directly into the machine room during winter operation. This method often requires frequent maintenance of the filter to maintain its dust removal function, and when the outdoor humidity is high, the directly introduced fresh air may Exceeding the allowable humidity range of indoor equipment may easily cause equipment damage, which is why the method of directly introducing fresh air cannot be promoted

However, if the outdoor temperature is low at this time, the heat exchanger must also adopt a high wind speed, resulting in waste

[0007] In addition, due to the limited space in the communication room, when the air conditioner and the energy-saving air heat exchanger are installed separately, it is necessary to choose the installation location, fix the installation, and connect the indoor and outdoor air pipes. Since the overall control needs to consider combined refrigeration and switching, the air conditioner and The separation of the heat exchangers is also likely to cause difficulties in cooperating with the respective controllers of the two
