The function of the HVAC system is to create a comfortable and healthy indoor environment. Increasing the indoor fresh air volume through appropriate measures is a very effective way to improve air quality. Generally, the larger the fresh air volume, the better the indoor air quality. Therefore, how to save energy consumption while increasing the amount of fresh air in the air conditioning system is another issue in the research of HVAC energy saving in recent years.
The heat recovery device is a device that performs heat exchange between indoor exhaust air and outdoor fresh air in an air conditioning system, thereby recovering heat in the exhaust air. At present, Kangjinghui plate heat exchangers are widely used in various heating conditions such as district heating, domestic hot water, swimming pool water heating, district cooling, heat pump, geothermal collection, ice storage, and pressure barrier.
The main applications are as follows:
① Daily hot water:
The good heat transfer performance makes the plate heat exchanger gradually replace the traditional container heating system, with a smaller footprint and more economical investment.
② Swimming pool water heating:
Install a heat exchanger to make the pool water circulate independently. To avoid the corrosion of the plate by the chloride ion in the pool water, please choose the plate material carefully.
③ Solar energy collection:
As one of the clean energy sources, solar energy has attracted more and more attention. By using a heat exchanger, the loop for collecting solar energy and the loop for domestic hot water can be separated, thereby effectively protecting the cleanliness of the loop for domestic hot water. Sex.
④ Ice storage system:
The use of heat exchangers in ice storage systems can isolate water and glycol solutions.
⑤ Ground source and water source heat pump:
The heat exchanger is used as a separation device between the host of the heat pump and the open heat and cold source, which overcomes the corrosion of sensitive equipment such as the host by water quality.
⑥ High-rise building pressure barrier:
In order to avoid higher system pressure in high-rise buildings, plate heat exchangers are used for regional pressure separation, thereby greatly reducing the large pumps and large pipelines used for customer service system pressure.
⑦ Open-closed circulating water system:
The use of heat exchanger separates the cooling cycle system from the closed cycle system of the unit, effectively protecting the cleanliness of the closed cycle system of the unit, and prolonging the service life of the unit.
