1 fan coil unit installation, carefully check the appearance before installation, commissioning tests should be stand-alone central air conditioning, if hear the sound normal, functioning smoothly. The system should be installed after the pressure test, the test pressure of not less than 6 kg (residential central air-conditioning). Experimental observation time of 24 hours, no leakage in compliance. 2, the unit should be set up stand-alone, hangers, installation location, height and slope should be correct, firmly fixed. 3, below the ceiling unit should be set aside inspection port to run maintenance work. 4, the unit with hot and cold water pipes, condensate pipes, ducts, flexible to take over the return air box or outlet connection to a central air-conditioning renovation Xuzhou, should be closely reliable. 5. During the installation process, you must note the following: do not touch (1) Transportation volute coil handling to prevent deformation of the scroll noise. (2) In order to ensure smooth drainage, in normal operation Xuzhou central air conditioning repair parts, the unit must be installed to ensure low noise, easy maintenance, condensate drain smoothly. (3) Saving the session can not be a foreign body accumulating, and all foreign bodies were cleared from the water dish to ensure smooth drainage path. (4) fan coil power line zero line must be connected to the specified zero line position, otherwise it will burn the motor. (5) does not allow a thermostat to control many different types of fan coil units. (6) When tightening the connecting pipes should be the correct approach. (7) is installed, add water to the front coil must open coil catchment head purge valve, the air inside the coil to be drained before the air drain valve is closed. (8) The machine must be installed coil connected to the outlet flexible connection and closing valves, shut-off valve is installed between the outlet and then soft connection. (9) the system is installed, the outlet size should be in written form to the user. 6, the outlet can not use white canvas, in order to avoid leakage. Storage air conditioning technology is the use of electricity at night when the grid trough for cooling or heating, cooling capacity or energy stored up, release cold or heat in the daytime peak electricity power shortage to meet the building needs air conditioning or hot water cold source . Storage conditioned the origin and development of water storage air conditioning international occurs at approximately 1930, initially for theaters, churches, dairy processing plants and other short-term use cooling load is concentrated place. This storage technology can bring large central air-conditioning cooling load Xuzhou recovery phone with a small refrigerator, it can reduce the initial investment of the refrigeration system. Later, refrigerator costs are significantly lower, application of this technology into a period of stagnation. 1973 energy crisis, once again draw attention to the air-conditioned cool storage. In the 1980s, the rapid spread of ice storage air conditioning technology developed in the energy shortage. In shopping malls, office buildings, commercial buildings, hotels, restaurants, entertainment venues, hospitals and other places application results are obvious. Japan to 2001 l storage air conditioning system has more than 15,000 sets. Taiwan, China since 1984 built the first ice storage air-conditioning systems, it has been put into operation by the year 2000 more than 600. From a global perspective, the world's developed countries have or are using storage air conditioning. The technology is currently in the world belongs to mature technology, world wide in various fields of application. South Korea has legislative 3,000 square meters of public buildings must use storage air conditioning system. Currently, the latest storage air conditioning is low, a large temperature difference between air cooling technology, few works have been done less investment than conventional air conditioning systems. Central air conditioning cooling transformation Xuzhou _ Sheng Erda (certified) _ central air conditioning is provided by Xuzhou 圣尔达 Refrigeration Electrical Services Limited. Xuzhou Sheng Erda Refrigeration Electrical Services Limited (xzktw.com) is in Xuzhou, Jiangsu, heat, refrigeration and air conditioning equipment leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs.
