Description

TECHNICAL FIELD

[0001] The present application relates to the field of ventilation and air conditioning, more particularly to a split-plate heat recovery system. BACKGROUND

[0002] Heat recovery as a way of energy saving and emission reduction in the field of ventilation and air conditioning is a general term for energy recovery, which can be divided into cold recovery and heat recovery. When the dirty air in the room is removed in summer, the cold air in the room is also taken away, and when the room is supplied with fresh air, the high temperature outside is taken into the room. In order to let the cold in the room be taken out as little as possible, the energy exchange between the exhaust air and the fresh air is used, and the heat exchange core is used as the medium for energy exchange. The heat exchange core transfers the heat of cold and hot air by being constructed close to the cross and not communicating with each other. In summer, the cold is recovered, and in winter, the heat is recovered. In addition to temperature, humidity also affects the comfort of the room. While the heat exchange core exchanges heat, the core with the function of absorbing moisture also absorbs and discharges water in the air. The heat recovery containing only heat exchange is called sensible heat recovery, and the heat recovery containing heat and moisture exchange is called total heat recovery.

[0003] When the indoor fresh air is exchanged, heat recovery can maintain small fluctuations in indoor air temperature and humidity, or reduce the subsequent cooling and dehumidification load or heating and humidification load. Because the single plate heat exchange core has an upper limit of air volume, when a large amount of fresh air is required, the most direct way to use the plate heat recovery is to combine multiple fresh air exchanger units, and the air pipe branching and merging, the cooling water inlet and outlet pipe, the drain pipe and other pipes are also branched and merged outside the unit. However, after combining multiple fresh air exchanger units, the air pipe system and the water pipe system are relatively complex, the air pipe layout is easy to interfere, and the fan start-stop is also relatively dispersed.
