Multi-operating mode energy-saving controlled combined type thermostatic and humidistatic air conditioning unit with thermometal compound box body structure

Abstract

The invention relates to a multi-operating mode energy-saving controlled combined type thermostatic and humidistatic air conditioning unit with a thermometal compound box body structure special for nuclear power stations. The air conditioning unit comprises a control system and a box body structure, wherein a primary-efficiency filter, a medium-efficiency filter, a surface cooler, a heater, a humidifier and a blow-off device are sequentially arranged in the box body; the front side of the primary-efficiency filter is provided with a fresh air and return air mixing section, and inlets of fresh air and return air are respectively provided with a fresh air proportioning valve and a return air proportioning valve; the control system adopts a programmable logic controller (PLC) and adopts air conditioning multi-operating mode zone control to realize the energy-saving operation of the unit; the surface cooler adopts a large temperature difference cold water heat exchanging technology and can save the investment and operation expenses of a water system; and the box body adopts a double-layer compound structure and an anti-shock device to meet the special requirements on the nuclear power stations. The invention has the characteristics of high efficiency, energy saving, good tightness, strong anti-shock capacity, safety, reliability, long service life, and the like.

Description

Technical field: [0001] The invention belongs to the technical field of air conditioning, and relates to an energy-saving double-metal composite box structure air handler for nuclear power plants. Specifically, it is an air conditioner capable of adjusting indoor temperature by adopting cold water large temperature difference heat exchanger technology and utilizing fresh air for cooling. Energy-saving, bimetal composite box structure combined constant temperature and humidity air conditioner with multi-working condition partition control combined with fan frequency conversion technology control. Background technique: [0002] In the case of energy shortage, people pay more and more attention to the issue of air-conditioning energy saving. The temperature difference of cold water in existing air-conditioning products is basically 5°C. If a larger temperature difference of cold water is used, such as 7-10°C, it means The flow can be greatly reduced by 30-50%, and the initial i...
