Carrying capacity of the air conditioner should mount a small air conditioner unit weight of less than 4 times 1) load. Carrying capacity of the air conditioner should mount a small air conditioner unit weight of less than four times. Mount bearing capacity outdoor unit at least not less than 180. Air conditioner outdoor woven material should not be loose mounting surface (such as the old house brick, hollow brick, etc.) Wall mounting; Gangan loading conditions shall be limited skills wall installation, the answer points to consider mounting surface material strength and endurance and quantity of carrier to a mounting surface mount air conditioner factor Xuzhou hand air conditioning repair, reinforcement or take protective measures if necessary, in order to ensure safe operation and personal safety of the air conditioner. (2) lock. When the air conditioner is installed, connect its mounting surface and mount between the mounting bracket and the unit should be solid, stable against second-hand air conditioning, make sure the air conditioner installed does not slip, tip over or fall off. (3) rust. Steel mounting bracket and steel fasteners should be less anti-rust treatment fluorine refrigerant bad, so much fluorine is not on good refrigeration it? Of course not! Evaporation pressure is high, the temperature of the evaporator is also high (words of the people is called the evaporator is not cold) since it is not cold evaporator and the ambient temperature of the temperature difference is small, the heat is also poor, how cool or heat will be better! So how do you know fluoro just good? Very simple way; evaporator dew or frost just over (if the relative humidity is relatively low, that is, relatively dry air humidity Xuzhou hand air conditioning repair parts, so the evaporator may not be able dew or frost)! People often ask; how fluoride, how much pressure is applied to the current standard is .... Generally evaporation pressure (low pressure) is half the equilibrium pressure. That is to say; refrigeration when (the machine operation) of pressure should be no half work before the machine, such as fluorine tank pressure 1.1Mpa Xuzhou brand used air conditioning prices, that about low pressure normal pressure is 0.55Mpa. The machine has a nameplate rated current, it refers to the standard current in standard operating conditions. But conditions of your work is simply not so standard, if you go by this current increase, it would be wrong. In general, this current is and condensing pressure (hypertension) is proportional to! (Some people say the current low pressure to go along with, and that is wrong, such as the press, the four-way valve string of gas, high pressure is not high, not low and low voltage, high current does not this time) will be subject to additional current voltage effect, higher voltage, current will be smaller, and some low-voltage, current will large! These high-frequency inverter air conditioner, current will be bigger, a little low frequency current is small. The pressure is the same; the inverter air conditioner turn faster, low pressure will be lower, the press turn slower, relatively higher pressure (so-called high and low pressure are relative balance in terms of) the frozen oil refrigeration engineering Role: 1, compressor lubricants in refrigeration engineering usually called frozen oil, which plays an important role in the operation of the refrigeration compressor. Under normal circumstances, oil change air-conditioning unit is factory run a cooling season (or heating season) to replace the oil once and then replaced periodically depending on the operating conditions. Because the unit during the assembly process, in order to prevent further leakage, use of welding methods, welding nitrogen welding process, but the filling of the nitrogen pressure is not big, big welding tainted point, that in the presence of air The case of welding, there are a lot of scale exist in the system, such as the scale of the refrigerant in the system operation, can hinder the transportation of oil from the minute the compressor rotor wear, and may block the oil supply capillary causing the unloading system failure, resulting in the unit normal operation can not be stable; 2, refrigeration compressor with lubricating oil during operation, lower compressor temperature, compressor seal the gap between acting parts and provide add, subtract load function, Therefore, the kinematic viscosity refrigeration oil, small amounts of moisture, copper corrosion, acid number and insoluble material must meet the standards. Through years of detection test, summed run need to be replaced once a year, time is running short in the northern region, can be replaced once every two years; Xuzhou second-hand air transfer, Sheng Erda refrigeration, air conditioning used by the Xuzhou 圣尔达 refrigeration appliances Services Limited. Xuzhou second-hand air transfer, Sheng Erda refrigeration, air-conditioning is used Xuzhou 圣尔达 Refrigeration Electrical Services Limited (xzktw.com) this year introduced a new upgrade, the above picture is for reference only, please call the contact or pictures on this page phone, for the latest information, contact: Liu Wanhai.
