Fan Coil Unit Transformation

fan coil unit transformation

China's fan coil has undergone several different changes in the process. Initially, the understanding of the fan coil unit to stay in the main requirements to meet the air volume on the basis of. That as long as the air volume to meet the requirements, is a good fan coil.

Under the guidance of this concept, the main characteristics of the fan coil unit produced at that time is that the air flow is generally exceeded, and then the unit noise is large and the energy consumption is large, and the unit power cooling capacity of the fan coil unit Only about 40W. As the noise is large, when the situation is that people enjoy the air conditioning to bring the cold wind at the same time, also had to endure annoying noise. In order to solve the above problems, the state began to modify the fan coil unit product standards.

China's fan coil manufacturing industry has developed rapidly, the annual output from the early eighties of the thousands of surge to tens of thousands of units, product performance has long been hovering in the foreign seventies level. This low level of rapid growth, the prospects are not optimistic. In the mid-eighties, the United States Trane, York, Carrier and other companies as the representative of the foreign fan coil manufacturing industry, have completed the upgrading of the product, and launched a new generation of products. At that time, China's air-conditioning industry is reveling in the domestic fan coil in the cold, noise and other isolated parameters close to foreign products and ignore the comprehensive performance and the use of the true gap between the results, so that this product can not be replaced in the air conditioning industry in China repercussions. In fact, the latest generation of foreign fan coil in terms of performance, variety and air conditioning should be ahead of our products. Fan coil is the central air conditioning ideal end products, fan coil is widely used in hotels, office buildings, hospitals, commercial and residential, scientific research institutions. It is understood that, in order to meet the design of different occasions, the type of fan coil is a lot of kind, horizontal concealed (back to the bellows) fan coil, horizontal mounted fan coil, vertical concealed fan coil, vertical Ming installed fan coil, card two wind fan coil, card four wind fan coil and wall-mounted fan coil and so on.

Selection of fan coil is a key issue. The choice of fan coil is the common practice in air conditioning system design. The purpose is to ensure the room temperature at peak load. And in fact the air-conditioned room to run most of the time will not be at peak load, so that the cooling capacity of excess, and switch to medium and low-grade operation to reduce the cooling output, thus maintaining the room heat balance. Select the fan coil unit, in addition to cooling capacity to meet the cooling load requirements, but also to meet their sensible heat and latent heat matching to meet the requirements of room heat and humidity ratio; air volume to meet the air temperature, Such as the use of requirements.
