<br> the home and home air conditioners central air conditioning system is very different in form, resulting in both in both before and after the selection, design, installation, maintenance and use have a greater difference.. Most consumers have home air conditioners .deeper understanding and awareness of this not going to repeat this, now only the home central air conditioning systems during the design and installation of the more common issues that experience like for. reference.. <BR> <BR> One, air conditioning ., lack of hot and cold load configuration <BR> <BR> 1, simply by using the area for air-conditioning hot and cold air-conditioning load of the configuration requirements of the indoor activities of personnel, for convenience, the adjacent .room. The door will always open, if they are opening the door of the room without air conditioning (such as: kitchen, bathrooms, changing rooms, etc.), the room air-conditioning system would be the formation of hot and cold load .the appropriate air-conditioning load, resulting in cold and heat load. configuration insufficient, which led to the room temperature is difficult to meet human comfort requirements.. <BR> <BR> 2, sample chamber and the actual development of cold .and heat load of the same configuration for the sales business needs, often in real estate has not been completed on a set or several sets of pre-chamber model of full-renovation show.. In cold and heat load configuration has ignored the actual completion .of the project when the difference between chamber.. I once handled a project of the A-type rooms, designed with cooling and heating loads according to the calculation of 3 tons of heat pump air conditioning cold and found that when the outside air temperature in .winter -2 ℃, the indoor temperature is less than the design requirements, while the air volume has to satisfy. requirements, resulting in owners are not satisfied.. The found that the model of the upper and lower left and right doors and windows of .adjacent rooms are not installed, the whole model around the room (hexahedron) are the outdoor enclosure.. Air-conditioning heat load recalculated and found to meet the original design parameters of the case, but also the lack of air conditioning heating capacity of 30 .%.. Here attention needs to remind the real estate developers, the introduction of model room, they should note that the model of the air-conditioning hot and cold load is configured in the above situation.. <BR> <BR> .3, the end of the cold air-conditioning load configuration enough, but consider different rooms simultaneously coefficient is less than 1, and air-conditioning capacity of the host is also configured by the corresponding coefficient, then, when all the end of all air .-conditioned rooms. When opened, the indoor temperature will be less than the design requirements.. <BR> <BR> Second, air conditioning, hot and cold load configuration has been enough, but the effect is not good <BR> .; 1, air-conditioning duct unit return air system, lack of air flow will lead to the problem is particularly prominent.. Mostly cause of back and return air duct area of less than (poorly designed).. Corrective recommendations: increase the return .and the return air duct size, or increase the return air ducts and return air.. <BR> <BR> 2, air supply and return air flow short circuit, Ji Song outlet has not sent all the delivery room air conditioning duct .air conditioning area, then return air flow to the area nearby.. <BR> <BR> 3, for the sake of convenience and savings, using long metal duct hose.. When the wind speed is greater than the metal hose 3m ./ s, its pipeline will be the rapid increase in wind resistance, while the home central air conditioner indoor unit fan pressure smaller.. If the information can not be too large to use air pressure to overcome the resistance, the actual air volume will be .significantly lower than the rated air volume.. <BR> <BR> Third, install the plumbing system within the machine test condensate smoothly, and running or running for some time and found to have water dripping phenomenon <BR> < .BR> 1, indoor hanging mount the upper and lower boom. spring washers at the nut is not set, when the device will be in the running after falling off his nut inside the machine vibration condensate tray to tilt the opposite direction, leading to condensation .of water overflow from the drip tray directly catchy.. <BR> <BR> 2, condensate pipe hanger spacing is too large, boom strong enough; particularly in the horizontal tube down the riser elbow take no hanger or hanger located away from .the elbow. too far, interior decoration, to push the riser, resulting in anti-coagulation pipe slope.. Therefore, installation of air conditioning condensate water must pay great attention to its pipeline to the rigidity and reliability of the slope.. In short ., the light has a good brand of household air conditioners is not enough, there must be a good air conditioning system.. The system is only set of painstaking planning and selection, well construction, well repair and maintenance in one, to give the user .a comfortable living year-round spring ...
