Compared with ordinary split air-conditioning, household central air-conditioning should be matched with the interior decoration. Household central air conditioning service, including not only the customer service service, including installation and sales before the consultation, design, construction. It can be said that to make a set of household central air conditioning system to normal operation, the importance of design, installation, construction as host equipment. Users in the purchase of household central air-conditioning, must choose the best service and good reputation of the enterprise, in order to protect their own interests. Thai Industriae experts believe that the selection of household central air conditioning to be divided into three steps.
The first step: determine the type of engine. First consider the size and direction of the housing, to see if there is a large area of the glass window, in order to calculate the maximum use of air conditioning at the same time. Generally speaking, in the ordinary home environment, the actual use of the cold is often not the total amount of room cooling, but lower than the latter, the former only needs to reach the latter 60% to 70%. The actual room required cooling capacity can be by the following formula calculation: actual cold area = housing construction area X housing practical rate X 65% (removal of the kitchen, bathroom and other non refrigeration area); actually cold = actual cold area X refrigerating capacity per unit area. Family of refrigerating capacity per unit area usually as per square metre 100 to 150 watts, if the room facing south, higher floors or wall of large area glass, appropriately increased to per square meter, 170 to 200 watts.
The second step: to determine the indoor machine and air outlet. According to the actual required cold quantity size decided to model, each room or hall only need a single indoor unit or draught, if the living room area is larger, or a rectangle can add a indoor machine or air, to need a horse or so for the standard configuration for each of the 12 square meter.
The third step: determine the layout of air conditioning. 1, the host should pay attention to the position of good ventilation and heat dissipation, easy maintenance, and try to avoid the influence of position of concealment, appearance and noise affect indoor house. 2, indoor position and interior decoration with the general layout, is embedded in the ceiling, the top can also be hidden in the cabinet. The indoor machine is ultra-thin, need only about 25 cm in height can be placed. 3, chiller refrigerant pipeline are fine, even if is coated on the outer surface of insulation layer can also be easily hidden; piping need full insulation, pipe fittings, valves and pipe contact with metal parts to insulation wrap up, to prevent the condensed water leakage; piping material selection of PPR pipe, PVC-U pipes and aluminium plastic composite pipe can ensure 50 years does not damage; all of the condensate to centralized or nearby concealed emissions.
