How water systems work
The water-cooled central air conditioner consists of four major components, a compressor, a condenser, a throttling device, and an evaporator. The refrigerant is circulated in the above four major components in sequence, and the refrigerant (refrigerant) from the compressor is heated and passed through the condenser. The temperature is reduced and the pressure is reduced, and the condenser takes the heat to the cooling tower through the cooling water system, and the refrigerant continues to flow through the throttling device to form a low-temperature and low-pressure liquid, flows through the evaporator, absorbs heat, and is compressed.
A chilled water circulation system is connected to both ends of the evaporator, and the refrigerant absorbs the heat of the chilled water to reduce the temperature of the chilled water to the user end, and then exchanges heat through the fan coil to blow out the cold air.
Wind system working principle
The fresh air transmission method adopts the displacement type instead of the internal circulation principle of the air-conditioning gas and the unhealthy practice of mixing old and new gas. The outdoor novel air is automatically sucked into the room through the negative pressure mode, and is installed in the bedroom, the living room or the living room window. When the fresh air inlet enters the room, it will automatically remove dust and filter. At the same time, the corresponding indoor pipeline is connected with the exhaust vents in several utility rooms, and the circulatory system will take away the indoor exhaust gas, and concentrate on the exhaust vents to "exhale", and the exhausted exhaust gas is no longer used for recycling. New and old styles with good circulation.
Coil system works
The working principle of the fan coil air conditioning system is to continuously circulate the indoor air by means of the fan coil unit, so that it is cooled or heated through the coil to maintain the required temperature and a certain relative humidity of the room.
The cold or hot water used in the coil is supplied by a centralized source of cold and heat. At the same time, the fresh air after centralized treatment by the fresh air-conditioning room was sent to each air-conditioned room through a special fresh air duct to meet the sanitary requirements of the air-conditioned room.
Compared with the centralized system, the fan coil air conditioning system has no large air ducts, only water pipes and small new air ducts. It has the advantages of convenient layout and installation, small occupied building space, and independent adjustment. It is widely used for temperature and humidity precision. Comfortable air conditioning with low requirements, large number of rooms, small rooms, and separate control.
