Integrated whole refrigeration air conditioning unit adopting surface air cooler and working method

Abstract

Provided are an integrated whole refrigeration air conditioning unit adopting a surface air cooler and a working method. The integrated whole refrigeration air conditioning unit comprises a modular magnetic suspension centrifugal water chilling unit, a cold water pump, the surface air cooler, a centrifugal fan driven by a brushless direct current motor, a silencer and an air purifier. The surface air cooler is a surface heat exchanger. The air purifier is formed by combining an electret static air filter and a light-free catalytic purifier. The cold water pump is arranged in an air conditioning unit box. A unit controller is arranged in the air conditioning unit box. The working method comprises the steps of performing filtration, sterilization and harmful gas removal on air through the combined air purifier, cooling and drying the air through the surface air cooler, performing noise reduction through a silencer and then blowing out the air. Due to the fact that the integrated whole refrigeration air conditioning unit adopts the modular magnetic suspension centrifugal water chilling unit and the centrifugal fan driven by the brushless direct current motor, the power consumption of the integrated whole refrigeration air conditioning unit is remarkably reduced by adopting the combination, occupied areas and spaces of a refrigerator room and an air conditioner room are decreased remarkably, and the energy-saving and emission-reducing effects are very obvious.

Description

technical field [0001] The invention relates to an integrated overall refrigerating and air-conditioning unit using a surface cooler and a working method. Background technique [0002] The combined air conditioning unit is one of the main air treatment equipment in the centralized air conditioning system, which has multiple functions such as cooling and drying, heating and humidification, and air purification. The main disadvantages of conventional combined air-conditioning units are: 1) Due to the large air supply volume, the supporting fan and motor are generally connected by belts, so the length of the fan section is relatively long, generally reaching 3-4m, resulting in a relatively large floor space for the unit. At the same time, due to the low efficiency and high noise of the ordinary motors and fans used, if the air volume is changed, an additional frequency converter is required, and the efficiency will decrease with the reduction of the air volume. 2) Except for s...

The main disadvantages of conventional combined air-conditioning units are: 1) Due to the large air supply volume, the matching fan and motor are generally connected by belts, so the length of the fan section is relatively long, generally reaching 3-4m, resulting in a larger unit footprint. At the same time, due to the low efficiency and high noise of the ordinary motors and fans used, if the air volume is changed, an additional frequency converter is required, and the efficiency will decrease with the reduction of the air...
