<br> <br> Household central air-conditioner details, and how the selection <br> <br> What is a domestic central air conditioning? <br> <br> Household central air conditioning (residential central air conditioning) is a large .central air conditioning in the whole air system and fan-coil system miniaturization of independent air-conditioning system. The cooling / heating principle and structure and large central air conditioner is basically the same, from a host of refrigeration / air duct heating, ventilation and .heat pipes connected or multiple end out of cold and warm wind equipment, will be sent to the different areas to achieve the purpose of the indoor air conditioning. It combines a large central air conditioning facilities, comfort, sophistication and traditional small split-simple, .flexible, and many other advantages that are suitable for villas, apartments, family housing, and a variety of industrial and commercial establishments. concealed air conditioning Household central air-conditioning as a very mature product, with its low price and excellent quality, nearly ten .years in Europe and the United States and other countries has been widely used, apartments and villas utilization up to 80%. In China, domestic central air conditioning in the last few years of sales and use of speed are doubled. <br> <br .> The types of residential central air conditioning? <br> <br> Common household central air conditioning generally can be divided into three types: <br> <br> Air cooling piping systems, wind and cold / hot water system, multi-type .system. <br> <br> 1) air cooling piping systems <br> <br> Air cooling pipe system is the most commonly used small family unit with central air-conditioning, simple structure, easy installation, construction period is short, inexpensive .! outdoor unit can consist of several compressor and condenser in a typhoon, indoor unit consists of evaporator and circulation fan, its number and compressor station must be the same as the number specified in a variety of forms such as concealed installation style, style, etc .. The system is characterized by the use of outdoor air cooled condenser, each compressor and indoor one-to-one configuration formation of independent systems, outdoor machine condenser and indoor connection between the evaporator tube for refrigerant tube upper, dark dress style indoor machines pipes .and can welcome indoor space situation can be air evenly arranged indoors, you can access the introduction of fresh outdoor air pipe. The system is completely dependent on refrigerant circulation complete air conditioning requirements, set by the chilling to air as a transmission medium, indoor air .(or the introduction of fresh air) cooling / heating is sent back to the room. The system is split air conditioning functions and conditioning of air. <br> <br> 2) wind cold / hot water system <br> <br> .Wind cold / hot water systems widely, from dozens of square meters to thousands of square meters, flat or multilayer structure, the room can be simple or complex. Unit of transmission medium is usually water or ethylene glycol solution. It hosts through outdoor produce air .conditioning cold / hot water, pipe system transportation to the Interior of the terminal device, the terminal units, cooling / heating water and indoor air thermal Exchange, cold / hot air, eliminating the room air-conditioning load. It is a focus on producing .cold / heat, decentralized treatment rooms air conditioning system. Cold / hot water units in the terminal device is usually the fan coil. <br> <br> Wind cold / hot water units for outdoor installation of the host, by the water tank and .one outdoor unit together; the outdoor unit of the refrigeration system, the water cooling in cold water through pipes will be sent to a room; the end of each pipe will need to connect the fan coil units, there are a number of forms you can .choose from: Ming loaded style, ceiling type unit embedded and concealed. In addition, water tanks and outdoor machine can separately, such as water tanks placed in the room (balcony, cellar, storage room, garage), the coldest in winter without will .let the water in the tank. <br> <br> 3) multi-type system <br> <br> More online-type systems applicable to the Office building. Unit to compress refrigerants for the transportation of the media, using a compressor .driven multiple indoor and outdoor host by lateral heat exchangers, compressors and other attachments. Indoor unit by direct evaporative heat exchanger and fan. Refrigerant flow and enter indoor heat sink of refrigerant flow, to meet different load on thermal moisture requirements. And other refrigerant type .air conditioning system of the main differences are: the system compressor adopting Inverter control, when the system is under low load by controlling the frequency controller, so that the compressor speed refrigerant circulation flow in the system can be changed to automatic control of the cooling capacity .to meet the requirements, on the General residential air conditioner system only needs to set a frequency compressors. In addition, there is a new type of dual compressor system, you can significantly reduce start-up current. <br> <br> Advantages: .can meet the needs of different rooms, energy saving, good heat comfort. <br> <br> The characteristics of domestic central air conditioning: <br> <br> 1) air conditioning effects <br> <br> 2) decoration effect .is good, high grade <br> <br> 3) quarter run <br> <br> 4) reasonable distribution of cooling capacity, maximum temperature effects <br> <br> 5) low one-time investment, long service life < .br> <br> 6) high efficiency, low energy consumption <br> <br> 7) refrigeration speed <br> <br> 8) introduced fresh air, improve air quality <br> <br> 9) ultra static sound design ., away from noise pollution <br> <br> 10) alarm protection system, use a more secure <br> <br> 11) stable quality, long service life <br> <br> 12) one outdoor unit, building appearance tidy .<br> <br> 13) model style and is equipped to meet a wide variety of household needs, especially for large sized <br> <br> Household central air conditioning system installation and repair <br> <br> For a small central .air conditioning, design and installation of it is very important, people often say: "a good air-conditioning system, 70% of the installation design, 30 per cent are machine quality." Construction process must be in strict accordance with the air conditioning .installation procedures and machinery installation requirements to action because the central air conditioning installation process complex and any negligence will result in very big trouble. Household central air conditioning is very mature and stable product quality, the whole machine long service life 15 years. .The sale of equipment according to the national standard implementing a complete machine warranty to three years, Compressor 3 to 5 year warranty, life-long maintenance. After-sales service, whatever the level of air conditioning products distributors, dealers, regional agent and the .Corporation triple pledge maintenance support, 24-hour on-site, professional, timely, credible and reliable. <br> <br> Household central air conditioning noise? <br> <br> Noise is very small. Even in a quiet night you .almost feel. Because, in the room host noise about 40 DB, well below the national standard, generally installed away from the bedroom hallway and living room and the corridor bedroom on the top, only air (no noise), unlike traditional split each room .hangs a indoor unit. Use household central air conditioner free of noise disturbance, guarantees a quiet home environment. <br> <br> Domestic central heating and air conditioning can be used in winter? <br> <br> Of course you can. .Household central air conditioning are available year round, summer refrigeration, excessive heat, winter heating period (additional auxiliary heating device), but also to introduce natural wind, make your room year-round. <br> <br> Without heating, full air .conditioning and heating can be used? <br> <br> Under normal circumstances, but in the outdoor temperature is below 10 degrees centigrade, the air conditioning heating effect is greatly reduced. Not only the central air conditioning, other split-type air conditioner .. There are ways to solve the above problems - in the central air conditioning unit of fan coil with a set of auxiliary heating unit (heater coil or hot water coil), even in low temperature conditions, central air conditioning also guarantee that the generation of .heat. <br> <br> Whether you want to install air conditioning in the decoration before? <br> <br> Yes. Horizontal dark dress-indoor unit and location of the pipeline requires ceiling, preferably before you install or repair and decoration .simultaneously; Ming installed-indoor ceiling, is not required to have completed the installation of interior decoration. <br> <br> Installation of household central air conditioning, not to the decoration work trouble and reduce room <br> Height? <br> .<br> Normally does. Indoor host using ultra-thin, thickness of only 23 cm, host and gateway to all rooms air duct are concealed in the corridor or local bathroom ceiling, in the living room and bedroom can only see the exquisite and unique .ventilation louvers, or finely craft ceiling molding, does not affect the original height of the room. <br> <br> <br> Use household central air conditioning, each room can free thermostat? <br> <br> Of course you can .. Each room is installed manually by the beginning or in the electronic thermostat outlet, you can adjust all rooms in the landscape. <br> <br> Household central air-conditioning host and air duct seal installation, maintenance and repair are in trouble? .<br> <br> Easy maintenance.
