Fresh Air Fan Coil Air Conditioning System and Its Application
Introduction
Fresh air - fan-coil air conditioning system, also known as air - water system, belongs to the type of semi-centralized air conditioning. The fresh air in the fresh air will be per person per hour need by air conditioning unit through the supply air duct
Details
In a fresh air fan-coil air conditioning system, the temperature of the air conditioning room depends on the coil of chilled water (or hot water) in the fan-coil tube and the small fan installed inside. In order to make up for the air pollution caused by indoor air circulation, people will feel more comfortable to send a certain amount of fresh air into the room through the fresh air system.
Fresh air - fan coil system can reduce the amount of fresh air, reduce the volume of air conditioning units and reduce the investment of equipment. In addition, it also has the characteristic of flexible layout. According to the situation, a fresh air unit can be set up in each floor (or the second or third floor) to supply fresh air to the air conditioning room of the floor, so as to reduce the volume of the fan coil unit air conditioning unit. Fan-coil units can be separately controlled indoors, and the air recirculation is limited to each room without causing pollution or bad smell in multiple air-conditioned rooms.
Fan-coil units are commonly used in large and medium-sized public buildings due to their simple structure, low noise during operation, small power and low cost. In some public buildings with low hygiene standards, only fAN-coil systems are installed, while fresh air is supplemented by the opening of doors and Windows or by infiltration, which can save the investment cost of fresh air treatment systems.
