What happens when the air energy water heater fan doesn t rotate? What should I do?

The air energy water heater fan does not die when the unit is cold and cannot be started. When the temperature drops below 0, the whole system will enter a shutdown state, even if the temperature rises, it still cannot start running, or the fan of the external machine rotates and the compressor stops working.

Analysis: The main reason for the unit to stop running is the control system, check the value of each set protection parameter one by one, such as the water temperature temperature difference control line, the system will not be able to start when the signal is not collected, because the unit is jointly controlled by the heat exchanger temperature and the temperature of the water collection tank and the set temperature, when the temperature of the collected water storage tank is lower than a certain value of the set temperature, the unit starts to start, when the water temperature of the collector part is higher than a certain value of the temperature of the storage tank, when the temperature of the hot water collection tank can not collect data, The self-protection of the unit is not activated. In addition, the voltage is too low and too high, the refrigerant is leaking, the compressor is low-pressure protection or the compressor has been broken, etc., the unit can not be started.

When the cold water pressure is not enough, the water storage tank cannot be replenished, and the unit will also be protected from starting.

Solution: First, check whether the compressor is damaged, measure the compressor resistance with a universal meter, confirm that the compressor is fault-free, focus on checking the control system, check the factory instructions of the unit or the engineering system design acceptance report, check the set parameters and measured data of the circuit, waterway and temperature according to the analysis, find out the non-conformities and correct them accordingly. When using a solenoid valve to control the water supply, check the sensitivity of the water level sensor and the size of the water pressure to make sure that it is not a problem with the water level data.

Air energy water heaters, also known as "air source heat pump water heaters". The "air energy water heater" absorbs the low-temperature heat in the air, vaporizes the fluorine medium, and then heats up and pressurizes through the compressor compression, and then converts the water into water for heating through the heat exchanger, and the compressed high-temperature heat energy is used to heat the water temperature.

Air energy water heaters do not require sunlight, so they can be placed at home or outdoors. After the water stored in the solar water heater is used up, it is difficult to produce hot water immediately, and if it takes a long time for electric heating, and the air can be hot water above minus 20 degrees Celsius, it can operate under pressure 24 hours a day. In this way, even if one tank of water is used, the air energy water heater will produce another tank of hot water in about an hour or even less.

At the same time, it can also fundamentally eliminate potential safety hazards such as electric water heater leakage, dry boiling, and harmful gases generated by gas water heaters.

What happens when the air energy water heater fan doesn't rotate? What should I do?

Hello dear. Answer: The main finch is happy to answer for you. 1. The reasons why the air energy water heater does not start are that the unit lacks refrigerant or leaks refrigerant Under normal circumstances, the air energy heat pump generally does not leak refrigerant or has less refrigerant.

The power supply voltage is not enough The normal starting voltage of the air energy water heater is 220V+-10%. In China's power supply system with a phase voltage of 220V and a line voltage of 380V, almost all compressors above 200V can be started. At 180V or more, 70-80% can be started, and at 160V or more, only a few can be started.

I've done it myself. Below 160V there is almost no possibility of starting. According to experience, when above 190V, the compressor starts the sock voltage more reliable.

3. Air energy heat pump failure: including compressor failure, high pressure failure, low pressure failure, insufficient water flow failure, etc., which need to be investigated, and the fault can be started normally. Fourth, the unit parameter setting problem, it is possible to reach the set temperature, or set the timing switch function, I hope the answer can help you, I wish you a happy life and good health.

1. The reason why the fan of the air energy water heater does not rotate:

The air energy water heater fan does not freeze when the unit is cooled and cannot be started. When the temperature drops below 0, the entire system shuts down. Even if the temperature rises, it still won't start, or the fan outside the machine turns and the compressor stops working. Analysis: The main reason for the unit to stop running is to control the control system, item by item, check the value of each group of protection parameters, such as the water temperature temperature difference control circuit, the system signal acquisition can not they will not start, because the unit opens the temperature of the heat exchanger and sets the temperature of the water tank and the set temperature of the three parameters of the joint control, the temperature of the collection tank is lower than the set temperature, and the beginning of each unit must be paid attention to.

Set part of the hot water temperature higher than a certain value to start the ring tank temperature, when the data collection is not the set temperature of the hot water tank, the unit to protect itself from starting. In addition, the unit cannot be started due to the voltage being too low, too high, the refrigerant is lost, the compressor is low-pressure protection, or the compressor is faulty. When the cold water pressure is insufficient, the water does not fill the storage tank and the unit is protected from starting.

2. Solution: First check whether the compressor is damaged or not, measure the compressor resistance with a universal meter, confirm that the compressor is fault-free, focus on the control system, control unit factory acceptance specification or engineering system design report, according to the analysis, check the set parameters of the circuit, waterway and temperature, measure the data, and find that it does not meet the corresponding and correct.

When using a solenoid valve to control water, check the sensitivity and pressure of the water level sensor to make sure that there is no problem with the water level data.

Analysis of the reasons why the fan does not rotate: 1) The pressure of the secondary high-pressure open-circuit system is too high. 2) There is no power supply.

3) The capacitor is broken. 4) The motor is broken. Sequential maintenance can be started from the following aspects; 1.

Check sub-high voltage switches, water systems, and freons for too much. 2.Check whether the power supply is in good condition and the electronic control board.

3。Check and replace the capacitors. 4。

Measure the windings and update.

The cooling fan does not necessarily run all the time, it is automatically controlled according to the temperature of the compressor and condenser, and it turns when it is needed, and does not turn when it is not needed.

Summary. Hello, the fan does not rotate is caused by the radiator icing, first to find the reason why the fan does not rotate, first confirm whether the fan is adjusted, and check whether the power supply voltage of the fan is normal.

Check whether the fan overheating protector is disconnected, check whether the resistance value of the fan is normal with a multimeter, and check whether the ground insulation of the fan is abnormal.

After confirming that there is no problem with the fan, try to jog the fan to test whether the fan can work normally.

In the case of confirming that the fan is normal, check the control line again, and check whether the control line of the fan contactor is loose and falling off.

The compressor has not stopped running, so there should be no fault alarm in the control interface of air energy, if there is a fault alarm, then the compressor should be in a stopped state.
