With the continuous development of modern society, the technology of central air-conditioning is constantly developing, and its application range is also constantly expanding. Compared with ordinary air conditioners, central air-conditioning will make the room more comfortable, and more and more families are in the decoration. Central air-conditioning is selected, and Trane central air-conditioning is an important brand in the central air-conditioning market. It is deeply loved by consumers. So what is the working principle of the US central air conditioning ? The following is a small series for everyone to introduce. First, the United States Trane central air conditioning working principle Refrigeration: 1. Liquid vaporization refrigeration is achieved by utilizing the heat release effect during liquid vaporization and condensation. The liquid vaporizes to form steam. When the liquid (refrigerant) is in a closed container, there is no gas other than the liquid and the steam generated by the liquid itself. The liquid and steam will reach equilibrium under a certain pressure. The vapor is called saturated steam, the pressure is called saturation pressure, and the temperature is called saturation temperature. 2. The liquid is no longer vaporized during equilibrium. If a part of the steam is removed from the container, the liquid must continue to vaporize to produce a portion of the steam to maintain this balance. The liquid absorbs heat when it is vaporized. This heat is called latent heat of vaporization. The latent heat of vaporization comes from the object to be cooled, and the object to be cooled becomes cold. In order for this process to continue, it is necessary to continually withdraw steam from the container and allow it to condense into a liquid before returning to the container. Heating: 1. The compressor draws in low-pressure gas and compresses it into high-temperature and high-pressure gas through the compressor. The high-temperature gas increases the water temperature through the heat exchanger, and the high-temperature gas condenses into a liquid. The liquid enters the evaporator and evaporates. (The evaporator also has a heat exchange medium while evaporating. The structure of the machine is different according to the media of the heat exchange. The air cooling and ground source are commonly used.) The liquid changes after passing through the evaporator. It becomes a low-pressure low-temperature gas, and the low-temperature gas is again sucked by the compressor for compression. In this way, the circulating water on the air conditioning side becomes hot water of about 45-55 degrees. The hot water is sent to the room where heating is required through the pipeline. The room is equipped with a fan coil to exchange heat between the hot water and the air for heating purposes. Second, the advantages and disadvantages of the introduction advantage: 1. High comfort: Each indoor unit of Trane Central Air Conditioning has one air supply port and one air return port respectively. The air circulation is more reasonable, the indoor temperature is more uniform, and the temperature can be maintained at ±1 °C. The human body feels more natural and comfortable, especially It is the central air conditioner of the water system, and the comfort is very high. However, the traditional household wall hanging machine and the cabinet machine are prone to airflow dead angles, and the indoor temperature difference is obvious, which is easy to get air-conditioning disease. 2, low cost of use: traditional split machine is affected by indoor environmental temperature changes, fixed frequency air conditioner compressor starts and stops frequently, power consumption is large, and Trane central air conditioner uses DC frequency conversion technology and new refrigerant technology, each indoor The machine can be controlled separately. Which room needs to be cooled to open the room, and the outdoor unit “outputs on demandâ€, so that the compressor is always in the best working condition, the power consumption is small, and the larger the room area, the more cost-effective to install the central air conditioner. . 3, long life: the life of household split air conditioners (wall mounts and cabinets) is between 5-8 years, while the life of household central air conditioners is between 15-20 years, of which, Trane central air conditioning water The system has a service life of 25 years. If it is a ground source heat pump central air conditioning system, the system has a service life of 50 years. Therefore, the service life of Trane central air conditioner is at least double that of the home machine. Disadvantages: 1. Complex installation: The installation of Trane central air conditioner is a complicated technical project. On the one hand, it needs to be synchronized with the decoration. On the other hand, the installation requirements are very strict. Under normal circumstances, the air conditioner is only half finished semi-finished after leaving the factory. The air conditioner must be installed at the end user. After the commissioning is completed, an air conditioner can be regarded as a qualified finished product. 2, large area: Trane central air conditioning generally requires a relatively large indoor area, it needs to be placed in the room to occupy a certain area, the same window and split type air conditioner is only installed on the wall and window, it is not suitable Used in small rooms. 3, large power consumption: Trane central air conditioning power is relatively large, generally more than 2 or more, so the power consumption is very high, work on the circuit requirements are relatively high, if the cross-section of small wires and small electric meters can not meet If necessary, it is best to use copper core wire and 20A or more meters to avoid possible hidden dangers. The above is the introduction of the working principle and advantages and disadvantages of Trane central air conditioner introduced by Xiaobian. Through the above introduction, we know that although there are certain disadvantages of Trane air conditioner, Trane air conditioner is still good, the cost performance of Trane central air conditioner, Quality and after-sales service are excellent in the central air-conditioning market.
