Do the two compressors of Gree water cooled air conditioner run at the same time?

It is running at the same time, the working principle of Gree air conditioner.

The air conditioner is mainly composed of two parts: the outdoor unit and the indoor unit. The outdoor unit is responsible for cooling or heating, and the indoor unit is responsible for transporting cold or hot air to the room, and transporting the hot or cold air from the room to the outside through the pipe to achieve the effect of cooling or heating up.

In the past, air conditioners were just simple refrigeration and heating and hot and cold air handling, with the innovation and progress of technology, now air conditioners have added many health functions and intelligent settings: 1. Air exchange function. Through the treatment of indoor and outdoor air, it can ensure that the indoor air is always new, fresh and natural; 2. Increase indoor active oxygen species and negative ions through special facilities, which is beneficial to human health; 3. Adopt frequency conversion energy-saving system to minimize power consumption; Fourth, the network is used to realize the remote control of the air conditioner.

After the air conditioner is started, it generally takes 15 minutes to reach the expected temperature effect, and people can connect the landline through the network before going home to send instructions, start the air conditioner, set the temperature, and when they go home, they can enjoy the "coolness" you need. In addition, in addition to focusing on health, energy saving, low noise and comfort, the current air conditioner has also innovated in appearance to make it more novel, fashionable and more decorative. The high-temperature and high-pressure refrigeration steam coming out of the compressor enters the condenser through the high-pressure hose; Since the outside temperature of the car is lower than the temperature of the refrigerant entering the condenser, with the help of the condensing fan, most of the heat of the refrigerant flowing in the condenser is taken away by the outside air, so that the high-temperature and high-pressure gas is condensed into a liquid with high temperature and high pressure.

When this high-temperature and high-pressure liquid flows through the throttle expansion valve, due to the throttling effect, the volume suddenly becomes larger and the pressure is lowered, and the mist liquid at low pressure and low temperature enters the evaporator, and vaporizes under constant pressure, because the temperature of the refrigerant in the vaporization in the pipe is lower than the circulating air in the car outside the evaporator tube, so it can absorb the heat in the air outside the pipe, so that the air temperature flowing through the evaporator is reduced, so as to produce the refrigeration and cooling effect, and the vaporized refrigeration steam is sucked and compressed by the compressor and becomes a high-temperature and high-pressure gas. Complete the cycle of a refrigeration system. Household ** air conditioner --Working principle Classification of household ** air conditioner Air duct machine A fixed-frequency outdoor unit, a fixed-frequency indoor unit, through the air duct to send hot and cold air to each room, can be convenient to introduce outdoor fresh air; It is also easier to humidify the air and other centralized treatment, it is a cheap machine, the design is reasonable, the noise of each room only increases by 1 3 decibels, the bedroom does not need to be suspended, and the temperature of each room can be higher than the temperature set by the main thermostat, and the temperature is controlled; There can be a certain proportion of energy transfer to achieve energy saving and speed up the cooling and heating speed of air conditioning.

They don't run at the same time, because there is only one motor, and if they run at the same time, it is impossible to achieve it, and it can't be brought up, so it can only be said that there can only be one machine running at a time.

The air conditioners of the two compressors are running when the temperature difference is large, and the temperature difference is a few smaller, it should be the operation of one compressor.

Five: fixed frequency machine failure**: e1:

Compressor High Pressure Protection E2: Evaporator Freeze Protection E3: Compressor Low Pressure Protection E4:

Compressor exhaust temperature is too high protection E5: Overcurrent (low voltage protection) Gree air conditioner troubleshooting example 1. Split machine Fault 1: No response after power-on (the light does not flash, the buzzer does not sound, and the remote control does not receive).

1): Inspection.

If this ** occurs, under normal circumstances, if his computer version fails, the computer version must be replaced, otherwise it will not work.

If Gree's air conditioner fails, it is recommended to find Gree's after-sales personnel to help you install and repair it in time.

Gree air conditioner display EC is water flow switch protection, air conditioning water flow switch protection, hot water water flow switch protection, the specific cause of the fault needs to be detected and dealt with by service personnel. Please click "Appointment Service" to self-service repair or call Gree National Unified After-sales Service** to feedback your needs and suggestions.

The use of air conditioning brings us a comfortable living environment, is now a kind of electrical appliances that everyone likes, so the use of air conditioning in our lives is more, among which the brand of Gree air conditioning is one that everyone prefers, so there are more people who use Gree air conditioning in the family, and we encounter more Gree air conditioning failures, there are many common Gree air conditioning failures, Gree air conditioning failures FC is one of them, then, Gree air conditioning failures What is the reason for FC? Let's introduce it to you.

You need to check the equipment manual, there is fault ** information in the manual.

Error** should be an installation problem with that system, and it is recommended that you reboot it.

Isolation water-cooled air conditioner error** means that the air conditioner is not running for the time being, you can check whether its wiring connection is normal.

If the communication between the controller and the host fails, it would be nice to provide the equipment model. It can be analyzed on a case-by-case basis. You can call after-sales service ** to find someone to repair, you can't solve it yourself.

Gree air conditioning compressors are mainly based on Lingda compressors, and also include some other compressor brands contracted for supply, which is subject to the actual situation.

Gree air conditioner water freezer failure B3 refers to the compressor (2) low pressure protection The cause of the failure is:

1. Refrigerant leakage.

2. The vacuum treatment of the system is not accurate.

3. Poor capillary welding and blockage, it is recommended to find professional maintenance personnel to check it.

The method of modulating heat from Gree water-cooled** air conditioner is as follows:

Turn on the remote control of the air conditioner, and the initial state is automaticClick the "Mode" button, and the adjustment status is refrigeration - dehumidification - air supply - heating. After adjusting to the heating state, then increase the temperature of the air conditioner, and generally adjust it to the highest temperature when the air conditioner is turned on for heating

Okay, plug in the air conditioner and turn it on with the remote control.

JR means heating, because the weather is cold outside, so the temperature of the refrigeration oil inside the compressor is low, and the compressor needs to be heated first. Then the compressor starts the preheating pipeline, and finally starts to supply air for heating, this set of procedures, you have to wait for more than ten minutes. So as long as you do it right, just wait patiently for a while.

Later, adjust the wind speed and temperature according to the demand.

Answer 3: After adjusting the heating mode of "main line control", you can adjust the heating mode to the internal controller of the internal unit in other rooms, and then you will find that other internal units can be set to the heating mode, and you can enjoy the warmth brought by the air conditioner.

Note: After setting the heating mode, the cooling mode of other rooms cannot be set, because this is the case for multi-online systems, depending on the cooling or heating mode set by the main line control.

Press the mode key or heating button on the control panel, switch to the symbol of the "sun" sign (some remote control will display heating in Chinese characters), and then adjust the remote control temperature to the range of 25-30 degrees, because the air conditioning heating needs to be preheated, slower than refrigeration, you need to wait for about 3-15 minutes after adjustment, it is recommended to wait for observation, in addition, Gree air conditioning can not be used against the season, heating is recommended to test and try when the outdoor temperature is below 20 degrees. Note: Only the heating and cooling models are available, and the single-cooling models do not support heating.

Press the mode button on the control box to convert the mode into heating operation.

1. After installing the battery, press the mode button, and the remote control will display triangles, snowflakes, raindrops, fans, and suns in turn;

2. The functions are automatic mode, refrigeration mode, dehumidification mode, air supply mode, and heating mode;

3, don't power on Gree first, press the remote control mode key, hit the sun (heating) mode, and then select the required temperature, 4, press the on/off key, turn off the remote control, power on the air conditioner, press the remote control to turn on the key, if the air conditioner does not have delay protection, the machine will start, then the outdoor unit first runs and preheats, the inner unit is not turned, this is the air-conditioning anti-cold wind function, wait for 3 5 minutes, the indoor unit reaches a certain temperature, blowing, heating begins.

Low-voltage protection, that is, less freon, or the low-voltage switch can be found to be measured with a multimeter, and if the low-voltage switch is measured under power failure and shutdown, it is a lack of freon.

Gree air conditioner failure**E3 is the compressor suction pressure too low protection, it is recommended to check:

1.Is the circulating air volume of the indoor unit too small?

Solution: Clean the filter of the indoor unit.

2.Not enough refrigerant in the system?

Solution: Add refrigerant.

E3 low-voltage protection, check the pressure of the air conditioning system, check the leakage point, the bell mouth, the wire connection, the globe valve, and the internal and external units to see if there is oil leakage, and the repair welding leakage point is operated according to the amount of fluorine added to the nameplate.

2.Fault **b3

Fault content: compressor low pressure protection.

Cause of failure: 1) Refrigerant leakage.

2. The vacuum treatment of the system is not accurate.

3) Poor capillary welding and blockage.

The compressor does not operate at low pressure.

Solution: Replace a 35UF compressor capacitor, and connect an auxiliary starter in parallel on the compressor capacitor, the air conditioner is turned on normally, and the compressor does not need to be replaced.

Pay attention to the following when installing an air conditioner:

1. Prepare the required welding equipment and the required suitable accessories and air conditioning copper pipes.

2. Be sure to clean the fittings and air conditioning copper pipes to be welded to ensure the correct solder joints.

3. Mark the copper pipe of the air conditioner you want to cut accordingly, and use a copper knife to cut the copper pipe of the air conditioner.

4. Wash both ends of the air conditioner copper pipe with an abrasive cloth or gauze cloth until it looks clean. This is done to remove dirt and grease and prevent oxidation.

5. Use air conditioning copper tube flux when welding, and only use a thin layer of air conditioning copper tube flux.

Fault Principle:

When the phase sequence of the three-phase power supply is wrong (single-phase is not applicable), and the overcurrent transformer of the external control board induces that the current is too large or there is no feedback signal transmitted to the indoor control board, the internal unit displays a fault and stops the machine. Under normal operation, the relay X1 (overcurrent, phase sequence relay) on the outer board should be in the suction state, and the voltage between the terminal 4 pins of the external machine and the live wire should be measured, and there should be 220V.

Solution: Look at the phase sequence, measure the current at the moment of startup, if the power on is E7, then invert the phase sequence and check whether it is a lack of phase, after pouring or E7, then change the phase sequence plate.
