Hisense Hitachi RAS-1010FSNQ motherboard into some non-substantive failure, families find it difficult to judge and eager to please people hands-on maintenance, thereby increasing the real failure caused by man, not only increases costs, but also affected the normal life of the family in the hot summer of and work. Therefore, in the context not immediately start to help readers improve home air conditioning use knowledge, improve their quality of life. A shutdown. Or will cause liquid hammer parts of the compressor and cause damage, affect compressor life. (Also known as latency protection) can automatically play delay protection. In less than three new intelligent air-conditioning in the microcomputer inside three minutes and then start the timer minutes can not boot protection is a normal phenomenon. Second, the air conditioner starts the first ten minutes and sometimes issue a "split shot" sound. The shell material is the use of air conditioning thin creamy white embossed plastic, light weight, elegant appearance, but it will change with temperature, thermal expansion and contraction of the physical phenomenon, it is air-conditioned "split shot" sound is slight deformation of the casing voice, not a fault. Third, when the air conditioning operation will occasionally produce some products like water "rushing" sound. This is the air conditioning operation, the internal state of the refrigerant is changing from a liquid to a gaseous state, and then back from gaseous liquid. This normal physical phenomenon in the refrigeration system with a flow velocity, due to a resistance of the water will produce a "buzzing" sound is normal. Fourth, the motherboard Hisense Hitachi RAS-1010FSNQ sent a slight odor wind. Some people think that air conditioning with the smell of the wind sent a freon leak caused. Freon is odorless but in fact, the smell of smoke from the room and other odors. The new air-conditioning efficiency through the use of activated carbon adsorption layer filtering strong, not only to remove tiny dust particles, but also remove the smell of smoke and other odors, purify the air greatly improved. Fifth, the indoor temperature does not drop down. Be the first to try his hand in the air conditioner and the air temperature without exception, if normal, then the air conditioner to malfunction. The cause may be due to indoor people, excessive heat, high outdoor temperatures, room windows are not locked, the curtains are not pulled tight, there is a heat source near the air conditioning, the room door switch frequently and so on. Sixth, the cooling operation, the indoor unit and poor ventilation, the wind is not too cold. New air conditioners generally use three filters, namely nylon mesh, electrostatic filter layer, activated carbon filter layer, high filtration efficiency, the ability to capture strong purifying small diameter dust particles of air, but the filter cleaning cycle becomes shorter. If not cleaned, there will be poor when access was blocked mesh, slow cooling air flow to reduce the phenomenon. 1, Hisense Hitachi RAS-1010FSNQ motherboard cooling in air conditioning design and manufacturing in general, allows the temperature control at 16 ~ between 32 ℃. When should the temperature setting is too low, while adding unnecessary power consumption, on the other hand cause the indoor and outdoor temperature is too large, the people out of the room can not adapt quickly to temperature changes, susceptible to colds. 2, Hisense Hitachi motherboard RAS-1010FSNQ desiccant air conditioning in the refrigeration process with dehumidification. People feel comfortable ambient relative humidity should be around 40 to 60%, when the relative humidity is too large as 90% or more, even if the temperature in the comfort range, people are still feeling poorly. 3, Hisense Hitachi RAS-1010FSNQ motherboard temperature heat pump heating and electric air conditioning has a function. Heating capacity with the outdoor ambient temperature decreases gradually become smaller, barely meet the heating requirements if the temperature at -5 ℃. 4, clean air in the air with a certain amount of harmful gases such as NH3, SO2, etc., and various odor, body odor, and the like bath lavatory foul odor. Air purification methods are: renewal wind, filtration, or the use of activated carbon adsorption and absorption photocatalyst. A, renewal wind: the use of the indoor fan system to the outside row of moist air, so that a certain degree of negative pressure room, surrounded by fresh air into the room from the door, Chuang Feng, improve indoor air quality. B, Hisense Hitachi motherboard RAS-1010FSNQ photocatalyst: in the light irradiation can be regenerated, the adsorption (closing) of ammonia, nicotine, acetic acid, hydrogen sulfide and other harmful substances freed, can be re-used. 5, increasing the concentration of air anion concentration of charged particles in the size of the air will affect human comfort. Installation of air conditioning can increase the negative ion generator aeroanion degrees, making the environment more comfortable, while lowering blood pressure, asthma and other aspects of inhibiting certain medical effects Tel: 18998013185 QQ: 415819311 Contact: Luo Lifeng cold Price: http://www.lengku1 . com / Hitachi compressor: http://www.hitachizg.com/ Hitachi inverter compressor: http://www.fuyid.com/ Hisense Hitachi compressor: http://www.fuyid1.com/ Hitachi inverter compressor Machine: http://www.fuyidg.com/ Hitachi chillers: http://www.hitach1.com/
