Do you know the difference between water air conditioner and fluorine air conditioner（VRV）？
Details
Now we can use air conditioning to cool down the indoor temperature. So the question is, do you use water air conditioner or fluorine air conditioner? First of all, let's compare how they work. "Water air conditioning" working principle: water system central air conditioning, composed of outdoor host and indoor terminal devices, provides air conditioning cold / hot water through the outdoor host, and is transported to the indoor terminal device by the water pipe system. Water and air at the indoor end, heat exchange to eliminate the room cold / heat load, is a kind of air conditioning system type that generates cold / heat centrally but handles the load of each room in a decentralized way In this paper. Working principle of "fluorine air conditioner": the central air conditioner of fluorine system takes refrigerant as the transmission medium and adopts variable refrigerant flow technology. The outdoor main unit is composed of outdoor heat exchanger, compressor and other refrigeration accessories. The indoor unit is composed of direct evaporative heat exchanger and fan. One outdoor unit can deliver refrigerant liquid to several indoor units through pipeline, and control the compressor control The circulating volume of refrigerant and the refrigerant flow into the heat exchangers in the room. Secondly, we can compare them from their comfort； Comfort of water air conditioning: "water air conditioning" uses water as the medium, cooling air supply temperature is higher, softer, more suitable for human physiology to accept the temperature difference, so the comfort is good.
The comfort degree of fluorine air conditioner: the temperature of cooling air outlet is low, the temperature suddenly becomes cold, the sudden change of temperature difference is harmful to human body, and the dehumidification is too dry. The human body feels uncomfortable. Therefore, after staying in the air-conditioned room for a long time, it is easy to have dyspnea, runny nose, sneezing, lethargy and dry skin. Finally, let's look at the advantages of water air conditioning 1. Air temperature control accuracy is general, noise impact is small, wall mounted furnace can be added in winter, with good comfort and little impact on air moisture content.
2. Second heat exchange, heating and cooling speed is slower. The air supply is soft and not dry.
3. The initial investment was slightly lower.
4. Water air conditioning saves water and electricity, refrigeration is fast, pollution-free, low price and no noise
The advantages and disadvantages of central air conditioning fluoride system and water system are obvious. The choice of central air conditioning fluorine system or water system depends on individual life style. The biggest advantage of fluorine system central air conditioning is "high efficiency", which is more suitable for buildings with an area of less than 200 m2. The water system is different. European and American countries, represented by the United States, prefer to enjoy a comfortable and healthy life. Therefore, the central air conditioning system of water system is more suitable for the large family high-end residential pursuit of comfortable taste. Whether you are oriental or westerner, you can make different choices.
