What use of gree air conditioning compressor
- Different models, different types of gree air-conditioning compressor used in the different. Anyway, now the air conditioning compressor manufacturers are also few: Hitachi, beauty cheese, panasonic, daikin, valley, sanyo, etc.s
Household air conditioning open is how liquid?
- A. Refrigeration condition: Connect the two outdoor pipe cap, valve with a wrench open. With five hexagonal wrench, in fine (high pressure valve) valve mouth, close the valve quickly, in about 20 seconds later turn off the thick valve (low pressure), and then shut down, without electricity. Such fluorine is received outside the machine. It can tear open machine.s
How to connect household air conditioning pressure gauge
- 1) check for the temperature of the fluid tube and muffler and condensation. Start the air conditioning runs under the condition of refrigeration 20 min, if any condensation on the outdoor unit back to the valve and the muffler, muffler fingered temperature was lower than that for the temperature of the fluid pipe, shows refrigerant in the system is enough, air conditioning running normally. Has one of following cases, indicates lack of refrigeration: (1) for the liquid condensation tube, muffler condensation; (2) for liquid pipe frost; (3) for liquid tube not dewing cool, muffler, nor too cold; (4) for fluid pipe and trachea is not cool. (2) measure the pressure of the valve in the back. Add the pressure gauge connected to air conditioning low pressure Angle valve inlet, measuring its operation at low pressure, under normal circumstances, when the environment temperature is about 30 ℃, refrigeration operation of low pressure is 0.45 ~ 0.55 Mpa, in heat pump air conditioning heating runtime should be 1.8 Mpa, if under the pressure, shows lack of refrigerant. The lower the pressure, the greater the leakage. If the basic pressure, explain refrigerant has. (3) fill nitrogen pressure (1.5 Mpa nitrogen filling the), observe the four two connecting pipe joint, gas liquid valve stem, and whether there is oil stains in areas such as the liquid mouth. There are oil stains for leaks. (4) using the leak detector to find the general part, and then coated with soap and water, if there are air bubbles appeared, to be funnelled namely. (5) of the heat pump air conditioning indoor unit and the connection part of pipe leak detection should be under the heating operation state, because of the inspected parts under high pressure, easy to find funnelled.s
What is the power of general household air conditioning?
- Home of the constant speed air conditioning refrigeration power (about) : 1 800 watts, 1.5 1200 watts, 2 1800 watts, 2.5 2200 watts, 3 2800 watts, 5 4600 watts. Constant speed air conditioning accumulative total working hour power consumption/c = refrigeration power present 1000. Example: 3 horse constant speed air conditioning refrigeration is about 2800 watts, accumulative total working hour power consumption = 2800 present 1000 = 2.8 degrees. No matter how many degrees of air-conditioning, 3 horse constant speed air conditioning are the refrigeration power of 2800 w in work, just open, different stop time. Air conditioning refrigeration, indoor temperature (for example, 30 degrees) and the difference between the set temperature: temperature difference (such as setting up 22 degrees), open long stopped short, don't stop, even more demanding; Little temperature difference (such as setting up 26 degrees), a short stop long, save electricity. Refrigeration power is "about", because of different brand of three air conditioning refrigeration power have difference, even the same brand of different models of three horse air-conditioning refrigeration power is not the same. Air conditioning refrigeration has stopped. The working time of air conditioning room area, set temperature and indoor temperature has long have short, measured the total work time of air conditioning is needed to faithfully to calculate the power consumption of air conditioning. Air conditioning, refrigeration power by day power consumption/c = present 1000 cumulative working hours.s
Heat transfer process in the central air conditioning system?
- The central air conditioning mainly by air conditioning compressor suction cold coal gas from the evaporator in the normal temperature and low pressure compressed into cold coal gas of high temperature and high pressure, sufficient heat exchange with cooling water in the condenser, cooling water absorbs heat, cold coal by using tower fan cooling pump to the cooling tower with the spray cooling water to heat exchange, Lin will heat released into the atmosphere; Then after cooling into cold coal low temperature and low pressure liquid, the regulator in the evaporator heat absorption of frozen water, into the normal temperature, low pressure cold coal gas to air conditioning compressor, single cycle finished cold coal; Cold and chilled water for coal in the process of evaporation heat is absorbed, becomes lower temperature of cold water, through the frozen pump to the end of the air conditioning equipment (fan coil) with indoor air heat exchange, aim to reduce indoor air temperature.s
Home air conditioner type and function
- According to the structure shape classification Window units: indoor and outdoor machine, applicable to small area of the room, installation is convenient and cheap price, but the noise is big. Fission air conditioning, without being limited by the installation position, are more likely to match with interior decoration, low noise, high quality needs to be installed. Made from fission type air conditioning: large power, strong wind, suitable for room large area, but the noise is big. Condole type air conditioning: take up little tiny, air supply distance, refrigeration effect is good, but being limited by the installation position, it is not easy to clean. Embedded air-conditioning: take up little tiny, beautiful and easy, air distribution area is wide, the cooling effect is good, but the cost is high. Central air conditioning, does not take up the interior space, no bare pipe, high comfort, no dead Angle, the wind out good decorative; But the price is higher, install complex. Air conditioning according to different classification of structure shape, the main can be divided into the window, hanging clothes closet, ceiling type, embedded, and central air conditioning, so a few kinds. Due to the different structural volume, take up the space also have differences, such as when the choose and buy, had better according to the size of space of the room, and so on and so forth to choose the right structure of the air conditioning.s
Household air conditioner 5 horses, whether need to change electricity
- Five of the air conditioning is to use 380 v three-phase electricity, if there is no three-phase electricity can't use. If the sitting room and dining-room together, had better add partition door, so the use of three air conditioning.s
What is the difference between separation and VRV air conditioning
- VRV variable refrigerant flow systems, belong to the split type air conditioning system. All direct evaporative cooling (water as cooling agent) can be called split type air conditioner. VRV equivalent to 1 drag a few household air conditioning, no water system (with the exception of condensed water). If the fan coil, general need chilled water system, the host into water chiller. Processor with air conditioning or fan coil. Choose what kind of air conditioning system, is a technical and economic comparison.s
