Application advantages and working process analysis of air energy heat pump

Air energy heat pump is to use the energy in the air to generate heat energy. It can provide 24 hours a day with large water volume, high water pressure and constant temperature to provide the family with different hot water, cooling and heating needs, and at the same time can meet the above requirements with the least energy consumption. The air energy heat pump works according to the "reverse Carnot" principle and the reverse Carnot cycle principle. Through the operation of the compressor system, the heat in the air is absorbed to make hot water. The specific process is: the compressor compresses the refrigerant, the refrigerant whose temperature rises after compression, produces hot water through the condenser in the water tank, and the heat exchanged refrigerant returns to the compressor for the next cycle. In this process, the air heat passes The evaporator is absorbed and introduced into the refrigerant, which is then introduced into the water to produce hot water. A new generation of water heaters that heat air through the compressor, namely air energy heat pump water heaters. Visually speaking, the "outdoor unit" compresses the air like a pump to raise the temperature of the air, and then conducts heat to the indoor water storage tank through a liquid that will boil at -17 ℃, and then releases the heat to conduct water . advantage: 1. "Safety + Saving Money + Comfortable + Environmental Protection + Durability" 2. High thermal efficiency: Because the heat pump water heater has a thermal efficiency of up to 300%-500%, the cost of preparing hot water is extremely low. 3. Heating and cooling integration: Air (heat pump) water heater integrates various functions such as hot water supply, heating, dehumidification, cooling, air filtration and other functions 4. It can also run at low temperature: no matter overcast, sunny, day and night, as long as there is air, hot water can be produced. The air source heat pump water heater is a highly automated equipment. The unit status is checked regularly when used. If the unit can be maintained and maintained for a long period of time, the operation reliability and service life of the unit will be unexpectedly improved.

How good is the air conditioning dehumidification

Nowadays, the temperature of some air conditioners is set actively by the manufacturer during dehumidification. Under the dehumidification method of this type of air conditioner, the control circuit will first check the room temperature, and then set the operating temperature policy value. The setting value of the factory plan is usually the policy value of the operation arrival It is 2 degrees lower than the room temperature. If the setting is too high, the dehumidification effect is not significant. In order to prevent overheating and lowering the room temperature during dehumidification, this set value is usually judged. At this time, we do not need to set the temperature, just open the air conditioning dehumidification function.<img src="{{media url="How_good_is_the_air_conditioning_dehumidification.jpg"}}" alt="" />

Working principle of air conditioner temperature controller

In the use of our home air conditioners, the most important function is to ensure that our indoor temperature is maintained at a relatively comfortable degree, and the air conditioner temperature controller is a tool to help us achieve this. What is the principle of controlling the temperature of our air conditioner by air conditioner? Today I will introduce some working principles and functions of air conditioner temperature controller for everyone to understand.

What are the causes of air conditioning trip

What are the causes of air conditioning trip 1. The contradiction between the rated current of the air conditioner and the current carrying capacity of the wire. 　　Here are two formulas involved: 　　①The rated current of air conditioner I=P÷U ÷power factor, the power remains unchanged, the smaller the voltage, the greater the current required. 　　② The current carrying capacity of the wire I=U÷R, the voltage is proportional to the current. 　　 So when the power supply voltage is normal, we must consider the line voltage drop. The longer the line, the greater the resistance, the greater the voltage drop, and the smaller the output current at the end. However, because the power of the load remains unchanged, the voltage becomes smaller, and the current that needs to be output will be larger. At this time, the wire is forced to overload, and the time will cause heating, and eventually cause the tripping of the open circuit. 　　 Some friends said that the heat of the wire will not cause the tripping of the circuit breaker. In fact, the manufacturer of the air switch has made it clear in the relevant manuals that the heat of the wire will cause the air switch to trip. Because the wire heats up, the crimp terminal will also heat up, and the resistance will become larger and larger. The larger the resistance, the greater the current consumption, and the hotter it will be, a vicious cycle. 　　 2. Leakage 　　During the daily maintenance work, we will encounter the situation that the air circuit trips due to the leakage of electricity. At least I have not experienced it once or twice. Regardless of the leakage of the neutral line or the leakage of the live line, a long time will cause the circuit breaker to trip. 　　Why does the electric leakage cause the MCB to trip? There are two situations. 　　 ① Good grounding. At the beginning, the leakage current was not large, and as time went by, the leakage current became larger and larger, and eventually evolved into a short circuit to ground, unable to close. 　　②There is no ground wire. If the equipment is not connected to the protective ground, when the wire leaks to the equipment, it is equivalent to adding a large shunt resistance. Like this problem, if the air conditioner does not have a ground wire, when the wire leaks to the air conditioner, the air conditioner is a very large shunt resistor and will consume a lot of current. Eventually, the wire will heat up or trip open. 　　How to determine whether the trip caused by the above two aspects can be done with a clamp ammeter. 　　 ① Measure the voltage at the input and output to see if there is a significant change in voltage drop. 　　②Measure whether the output current exceeds the standard. 　　 So my suggestion is: first measure the supply voltage to see if it is within the allowable fluctuation range. Then measure the current to see if it exceeds the rated ampacity of the wire. Finally, check the data one by one according to the measured data to find out the reason.

The main reason for the slow heating of air conditioners

There are several reasons for the slow heating of air conditioners: 　　 The dirt of the transpiration device and the condenser is too thick, which will cause air flow blockage, affect the heat declaration, and make the air conditioning heating a big discount.

How to properly clean the air conditioner yourself

After a winter of inactivity, the air conditioner that has been "dusted" for a long time is reactivated. It is believed that most of the friends are directly plugged in and turned on. In fact, this is not correct. <img src="{{media url="How_to_properly_clean_the_air_conditioner_yourself.jpg"}}" alt="" /> It is necessary to know that the air conditioner has accumulated dust and breeds bacteria after being left for a long time. Blowing out with the wind seriously threatens your health. This is actually due to the working principle of the air conditioner: when cooling, the room temperature air is continuously sucked in, filtered by the filter, and then cooled by the fins of the heat exchanger, and finally the cold air is blown out, and then returned to the room for reciprocating circulation.
