Q:How many degrees electric air conditioning in a day
Air conditioning of electric power is 800 ~ 2000 watts range Large cabinet air conditioning 2000 watts General air conditioning around 800 w ~ 1200 w (of course, vary according to the temperature and air flow) Suppose someone home air conditioning electric power of 1000 watts 24 hours should be 1500 watts when = 36 kw * * 24 (c) At present the electricity price is 0.48 yuan/degree of Beijing For 36 * 0.48 = 0.48 yuan In other words, depending on the air conditioning, electricity will have differences, but generally in 15 ~ 20 yuan (suspension) The scope of 30 yuan (the cabinet)
Q:Air conditioning machine which is high pressure pipe? Which is of low pressure pipe?
Cooling tube for high pressure, tubes for low pressure pipe. The working principle of air conditioning: compressor, condenser, throttle valve, evaporator, Reduce the compressor refrigeration: the high temperature and high pressure gas entering the condenser, in the outdoor condenser absorbs heat to high pressure liquid at room temperature, and then enter the throttle valve after decompression low pressure low temperature of liquid, entered the room after the evaporator absorbs the heat of the room into a low pressure gas at room temperature, then in the compressor, the cycle of the cycle. Heating: high-temperature high-pressure gas from compressor discharge directly into the room of the condenser heat absorption cooling in the room into a high-pressure liquid at room temperature, and then enter the throttle valve, the step-down into low pressure low temperature liquid, then after the evaporator absorbs heat into outdoor outdoor low temperature gas in the compressor, the cycle of the cycle. Actually is evaporator condenser, condenser and evaporator, they're just different in cooling and heating function known as condenser or evaporation. Air conditioner: when heating by the compressor, four-way valve, valve, outdoor heat exchanger of indoor machine, cooling pipe, valve, capillary, condenser, electromagnetic four-way valve, receiver, condenser, compressor.
Q:Air conditioning is divided into several types
Roughly the fission and window machine. And there came of the changes in temperature and used by, and heat pump, electric auxiliary heating, etc.
Q:What kind of air conditioning is best save electricity?
In fact, air conditioning power consumption big; Basically see use method. For example set temperature is 16 degrees, so the air conditioning that decide frequency of compressor is impossible to stop, so how much is the nominal power consumption, power consumption is easy to calculate. If it is frequency conversion air conditioning units, set temperature 16 degrees, air conditioning units may have been running in the high frequency high power, power consumption may be more than fixed frequency. If the set temperature is 26 degrees, fixed frequency can be intermittent operation, we can reduce the frequency and frequency power operation, power consumption can than nominal power consumption is low, can achieve the result that province can save electricity.
Q:The demolition of household air conditioner?
Air conditioning units operating process: Switching (including replacement of indoor machine or need to recycle refrigerant), violate compasses operation may cause refrigerant recycling compressor, air conditioner switching is also a kind of frequent business, all need to be in the process of switching refrigerant recycling, but if the improper operation, will also be the worst effects of the compressor explosion. Operation: compressor running low voltage side to close the high-pressure valve, air conditioning system to run for a few minutes, the compressor suction air leakage explosion. Funnelled process analysis: due to air conditioner refrigeration system, the system internal cause low voltage side is funnelled has no refrigerant or a small amount of residual refrigerant, cause the compressor suction air and close running on the high side, the final explosion. Compressor explosion: the mechanism of air conditioner refrigeration cycle system high side blocked - compressor running to inhale air for several minutes, the compressor overheating - frozen oil overheating vaporization - compressor inside a huge increase in oil and gas mixture, temperature, pressure increased to achieve a certain pressure, temperature, mixture combustion of oil and gas compressor, a sharp rise in the temperature, pressure and compressive strength than the compressor shell and the compressor shell burst. Response: in front of the air conditioning switching operations, you must first open air conditioning to check operation parameters. Confirm the various performance parameters of the normal pressure gauge on the three-way valve process pipe connections, can close the high-pressure valve for refrigerant recovery, downtime when pressure is 0.1 MPa.
Q:What's good for home air conditioning
10, if there is a low voltage automatic compensation function, has a wide working voltage. When in addition to buy air conditioning to look at the fin of evaporator, condenser, neat rows of rolled piece without damage, ribbed closely associated with copper pipe, not loose. Check running status of air conditioning, start the air conditioner to see any abnormal noise in the operation of the compressor; Fan operation is normal, high, medium and low speed have obvious difference, low noise; There are flat, beautiful appearance and a good quality plating. 11, try to choose low carbon air conditioning to reduce carbon emissions, low carbon environmental protection, protect the earth. Buy air conditioning must not only see the brand of air conditioning, buy the beautiful air conditioning or gree air conditioning these big brand is ok, but must be a good pick! The hope can help you!
Q:What type of refrigerant home air conditioning?
Household air conditioner commonly used models with R22 and R410a refrigerant. R22 used in air conditioning that decide frequency, due to the destruction of the ozone layer has a certain effect, therefore is a kind of transitional refrigerants. R22 features: At room temperature for colorless, approximate tasteless gas, not burning, explosion, corrosion, toxicity than R12 slightly larger, but is still a safe refrigerants, security classification for A1; Pressure can be liquefied colorless transparent liquid. Chemical stability and thermal stability of R22 are very high, especially in without the presence of moisture, can't afford to under 200 ℃ and general metal reaction. In water, only with alkali slow work. It happens in high temperature cracking. Available as refrigerant R22 is a kind of low temperature, refrigeration temperature to 80 ℃. R410a used in frequency conversion air conditioning. It is a new kind of environmental protection refrigerants, does not destroy the ozone layer, the working pressure is about 1.6 times that of ordinary R22 air conditioner, refrigeration (warm) of high efficiency and improve the performance of air conditioning does not destroy the ozone layer. R410a features: New refrigerant R410a is composed of two kinds of quasi azeotropic mixture of R32 and R125 each 50%, mainly include hydrogen, fluorine and carbon (HFC), has the stability, non-toxic, superior performance, etc. At the same time as a result of not containing chlorine, so will not react with ozone, which does not destroy the ozone layer. In addition, the adoption of new refrigerant of the air conditioning in terms of performance also improved. R410A is by far the most appropriate internationally recognized to replace R22 of refrigerant, and in Europe and the United States, Japan and other countries. R410A replacement in the main international market of global trends and prospects of using condition and the dynamic of entering the international market.
Q:Household air conditioning use a fixed frequency of good or a good have what distinction
Don't consider the price problem, stand in a comfortable and energy saving application point of view, frequency conversion air conditioner. The advantage of frequency conversion air conditioning: 1, early on, the high frequency operation, and can quickly to set temperature at room temperature. 2, when reach the set temperature, slow running non-stop, room temperature changes within the plus or minus 0.5 degrees C, small changes, comfortable. After 3, stable operation, low frequency low power operation, energy saving province electricity.
