What it needs to add refrigerant air conditioning does what it needs to add refrigerant air conditioning it? Some people think that the difference is the need for air conditioning and refrigeration effect to add refrigerant, in fact, not the case, air conditioning and refrigeration effect is not good, there are many cases, such as the four-way valve string gas, compressor leak, capillary blockage, etc. are possible, The following specific analysis of air conditioning not cooling: air conditioning refrigeration case there are many, there are three situations: First, the voltage is too low, the supply voltage can not run the air conditioning; the second is the air conditioning unit environment is poor, poor ventilation causing blockage outside the machine; Third, the lack of fluoride. "The first two cases occur frequently, and air conditioning because of the lack of fluoride is not really the case less cooling." Wang said, residents of the home's air conditioner is not cooling, first find the first two reasons, and often clean air filter. "If there is frost on the straw air conditioning unit, it is likely to be true lack of fluoride;. If you are unsure, ask a professional repairman detection measurement tools," Wang said. Improve the effectiveness of air conditioning and refrigeration method - air conditioning repair, air conditioning repair evaporation temperature factors are the following: 1. Evaporator oil pipeline junction: Under normal circumstances because of the lubricating oil and freon solubility Xuzhou central air conditioning cleaning, the heat exchanger surface is not will form a film, the film can not be considered resistance, but in the case of additional lubricant, you must use the same label as the original oil, to prevent the film's production. 2. dry filter clogging: To ensure the normal cycle refrigeration Ji, the cooling system must be kept clean, dry, and if there are impurities in the system, it will cause dry filter is clogged, the system for liquid difficulties affect the cooling effect. 3. The air filter is clogged: filters must be replaced periodically to ensure that the required air volume air conditioning cycle. The refrigerant is too small, additional freon. Condensing pressure air conditioning repair air conditioning condenser cooling systems generally dirty room air conditioning with air-cooled condensers Xuzhou central air conditioning parts, which consists of multiple sets of coils consists in external coil fins to increase the air-side heat transfer area, and at the same time , using the fan accelerates the flow of air to increase the heat transfer effect on the air side. Because films from smaller, with CRAC continuous prolonged use of central air conditioning, debris and dust flies glued to the condenser fins, resulting in large air can not flow through the condenser, the thermal resistance increases, the influence of the heat transfer effect, leading to condensing effect is reduced Xuzhou central air conditioning installation, the high side pressure increases, the cooling effect is reduced at the same time, consume more power, the condensing pressure is increased by 1 kg / cm2, electricity consumption increased by 6% to 8%. Solution: Use the environment combined with air-conditioning, according to knot gray case, the air conditioning unit on a regular basis to wash, the specific method is to use water gun or compressed air, rinse conditioner condenser from the inside out, remove debris and dust attached to the condenser to ensure Meanwhile good cooling effect, saving a lot of energy. Air shift attention to what moves when confidential deliberately brass split off, get a new pipe to deceive customers. Deliberately valve does not open or semi-open to loss of fluorine in the name of increased costs, such consequences or cause performance degradation when the compressor is bad, or when the four-way valve moves, such as wiring and heating in winter and then unplug the door to deceive customers. Before moving machine is good, bad, or can not afford a machine malfunction or remote and backward refrigeration machine / heat effect is poor, it is a small relocation experience and technology, however, the consequences will burn out the circuit board. How much horsepower for maintenance of air conditioning, plus how much fluoride, a current much, much power, cooling / heat did not know how many calories, but mechanical maintenance, not theory with practice, so that failure due to small and large, that the whole scrapped. Based on the above examples, I remind customers of wedding dresses, looking for regular maintenance company.
