What is the effect of adjusting the set temperature of the air conditioner on the high and low volta

What do you mean by high and low pressure? Does high voltage refer to 220V mains?

Whether it is a fixed frequency air conditioner, the temperature adjustment is only to adjust the working power and time of the air conditioner (the frequency conversion air conditioner is to adjust the working frequency of the compressor, so as to achieve the regulation of stepless speed change, but there is no difference between the overall electrical principle and the fixed frequency), there is no impact on the voltage (no matter how high or low), there is an impact on the current, that is, the power consumption will change with the set temperature. When the voltage is constant, the power consumption increases, and the current will also increase.

The air conditioner temperature is set at 26 degrees Celsius to be comfortable and less susceptible to illness. When using the air conditioner, it should be ensured that the temperature difference between indoor and outdoor is not too large, generally about 8 to 10. In summer, although there may be a high temperature of 38 or more, the temperature is below 35 most of the day, so an indoor temperature of around 26 is more appropriate.

And generally after two or three hours of turning on the air conditioner, you should open the window to ventilate, about half an hour or so. There is no natural wind convection, the air is dirty, and it is easy to get tired and have headaches.

Extended information: Whether the air conditioner is cooling or heating, it can set the maximum temperature of 30 and the minimum of 16, and this temperature limit value is only applicable to the air conditioner of fluorine refrigerant system; In the case of other refrigerant systems, the temperature range can be extended to both sides, e.g. as low as 5 and as high as 60.

The minimum temperature of the current household air conditioner in China is 16, which is mainly considered from the perspective of energy saving and human comfort. In the summer, the outdoor sun is like fire, sweating into the low-temperature air-conditioned room, suddenly refreshing, but the coolness is only temporary, after a while it is very likely to catch a cold, so the air-conditioning temperature must not be set too low for the sake of coolness, too large temperature difference is also not good for health, not only easy to catch a cold, but also easy to heat stroke.

Almost no effect, fixed frequency machine. Inverters will have different pressures depending on the frequency.

Air conditioner low pressure high high pressure low what is the problem.

Hello, glad for your question! Air conditioner low pressure high high pressure low What is the problem that the compressor displacement does not meet the requirements, and the expansion valve is faulty. 1. In the case of normal operation of the air conditioner, the low pressure is about 3bar, and the high pressure is about 15bar, pay attention to the normal operation of the air conditioner, that is, the cab blower is turned on to the fourth gear, the cooling fan of the water tank rotates at high speed, and the external condenser carries back the heat dissipation well.

2. Caused by electrical appliances: compressors, solenoid valves, four-way valves, abnormal operation of motors, etc.; 3. System: refrigerant leakage, nuclear hunger blockage, heat exchanger finger dirt, etc.

Hello, it may be the following reasons: the air conditioner has the problem of high pressure and low pressure, the main reason is that there is a problem with the throttling element or a dirty blockage in front of the throttling element, and the valve is not fully opened. First of all, check to confirm whether the high and low pressure shut-off valve is fully opened, and check whether the throttling element is normal.

In general, under the normal state of air conditioning and refrigeration, the normal value of the blue meter (low-pressure pipeline pressure) is 2-4bar. The red gauge (high-pressure line pressure) is normal for 15 bar. (1) Power supply problems (too high or too low voltage, thin power cord diameter, insufficient switching capacity); 2) The current of the compressor over the source (short circuit between the turns of the compressor, holding the shaft, stagnation, lack of refrigeration oil); Hail section (3), large load on the external machine (poor heat dissipation, dirty surface of the condenser, sunset, etc.); 4) The system is high-pressure side plug or semi-block; (5) Excessive refrigerant charge; (6) The current transformer of the main control board is short-circuited or the current detection circuit is faulty;

1. The temperature sensor switch loses the orange effect, so that the valve is in a normally closed state, and the expansion valve and drying bottle should be replaced.

2. There may be air in the pipeline or the air inlet caused by poor sealing, and the refrigerant should be re-emptied.

3. If the pipeline system is blocked or the expansion valve is blocked, replace the expansion valve and clean the pipeline.

4. If the refrigerant is excessive, it can be completely evacuated, and then the refrigerant can be added quantitatively.

5. The air conditioning system has poor heat dissipation, the condenser may fail, and the internal and external grilles of the condenser need to be cleaned, as well as the dirt of the radiator grille of the water tank, and replaced if necessary.

6. Cooling fan failure, engine overheating, excessive or insufficient refrigeration oil.
