How to clean a commercial air energy heat pump tank

Air energy heat pump cleaning water tank is a big project, such as cleaning can not stop the water, for fear of damaging the unit, this operation is best to ask professionals, but some air energy water heater tank has a special sewage nut under the tank, this kind of direct sewage nut can be discharged by unscrewing the sewage nut. If there is no special sewage nut, you can remove the water pipe with a safety valve on the right side and the safety valve to discharge the water and drain the sewage. In this way, although there is a discharge of sewage, but there is still part of the residual water at the bottom of the water tank can not be released, it is best to go to the market to buy a water dispenser, and suck out the sewage according to the siphon principle, so that the water tank will be clean after several flushes.

1. Shut down and cut off the power switch 2. Do not touch with wet hands 3. Do not clean with hot water or solvent 4. Maintenance of the safety valve: the handle of the safety valve should be rotated once a month, if there is water flowing out, it means that the safety valve is working normally, if there is no 5. Liner drainage: cut off the power supply, close the water inlet valve, open the safety valve for pressure discharge, when there is no water outflow, close all the outlet valves, remove the drain pipe of the safety valve and the wire with a wrench, and then open the sewage port plug, and connect the drainage pipe and the wire to the sewage outlet ( The other end of the drain pipe is placed at the mouth of the sewer), open any outlet valve, drain the drain, and discharge the clean water from the drain pipe to indicate that the inner tank has been drained, and install all the parts back in place.

Note: During the sewage discharge process, the water inlet valve should be opened several times to flush the dirt at the bottom of the inner tank. 6. Emptying of the water tank

When moving or not using the water heater for a long time, please empty the water tank according to the above method of draining the inner tank. 7. The protective anode rod (magnesium rod) configured in the water tank of the air energy water heater can prolong the life of the product. Magnesium is a very active element that can be used to displace calcium ions on the surface of water and prevent the formation of scale.

Generally, it is necessary to replace the magnesium rod once every two years, but the replacement time varies depending on the water quality in the region.

1.For the air energy heat pump tank equipped with a blowdown nut, if you want to clean the spring lead of the water tank, you only need to open the blowdown nut directly to discharge the water and drain the sewage. Bright letter.

2.For the air energy heat pump tank without a blowdown nut, you can remove the water pipe with a safety valve and the safety valve to discharge the water and drain the sewage, but there is still waste water at the bottom of the water tank, which is difficult to discharge, it is best to buy a water suction device, suck out the sewage, and finally rinse it with clean water several times to wash it clean.

<> first determine whether the air energy water heater has a blowdown valve, if so, open the blowdown valve after the power is turned off, discharge the water directly, and then fill it with water after cleaning, and repeat it several times to clean it. If there is no blowdown valve, you need to remove the water pipe and safety valve with a safety valve on the right side to complete the drain cleaning.

For specific operations, please refer to the following steps:

1. Some air energy water heaters have a special sewage valve under the water tank, and this kind of water heater can directly open the sewage valve to discharge water and discharge.

2. When the water in the water tank is almost discharged, the scale in the water tank will be brought out. After draining the water, close the blowdown valve, add some clean water to the water tank, and then open the blowdown valve to release the water, so that the scale in the water tank can be cleaned up several times.

3. Some air energy water heaters can discharge water and sewage by adjusting the angle of the safety valve, but the water discharge is too slow and the effect is not good;

4. For water heaters without special sewage valves, it is best to remove the water pipe and safety valve with a safety valve on the right side and discharge the water and drain the water.

If the water heater does not have a blowdown valve, it is necessary to clean the water tank as follows:

1.Turn off the air energy water heater and turn off the power, and be careful not to operate it with wet hands to avoid unnecessary risk of electric shock.

2.Open all the outlet valves, drain the water, and when the water is clean, fill the tank again and empty it again. Repeat this several times until only clear water comes out.

3.If the water quality is still not clean enough after repeated water inlet and discharge operations, you can consider replacing the magnesium rod in the water heater. In general, magnesium rods need to be replaced every two years.

4.After confirming that only the water is flowing out, turn on the power, close all the outlet valves, and then open the water inlet valve, and fill the water to complete the cleaning of the water tank.

This answer is applicable to most brands of water heater models such as Haier, Wanjiale, and Midea.

First, the pipeline filter is cleaned, first of all, the Y-type filter on the pipeline is removed, and the impurities on the filter screen in the filter are rinsed. Then put it back in place.

Second, the evaporator is partially cleaned, and the special heat pump fin detergent is evenly sprayed on the evaporator with the water mixture.

Wait (5-10) minutes for the impurities on the evaporator to detach from the evaporator. The evaporator is then rinsed with a high-pressure water spray gun.

Third, for condenser (replacement) cleaning, first mix the citric acid cleaning agent with water evenly. Use a water pump and already.

The prepared citric acid cleaner is used with the condenser (set change) for circular cleaning. Cycle (20-30) minutes to drain the citric acid cleaner. Then use tap water and condenser (set change) for circulating cleaning.

Cycle (5-10) minutes to drain the tap water. Repeat (2-4) times with tap water.

The press does not work, the water pump works, and if the scaling is serious, it can be cleaned with oxalic acid solution.

If you use a Finney's air energy water heater, there is generally no need to clean the water tank because there will be no limescale.

The cleaning method of the outdoor unit of the air energy water heater is the same as that of the outdoor unit of the air conditioner, using a weak alkaline solution or a special "dust cleaner" to clean the dust and dirt on the surface of the heat exchanger, and rinsing the residual cleaning solution with tap water after cleaning.

The cleaning of the inside of the water tank of the air energy water heater is the same as that of the storage electric water heater, open the blowdown valve, and drain the sewage while filling the tap water, or fill a certain amount of weak alkaline solution into the water tank before flushing.

Finney air energy water heaters generally do not need to be cleaned.

The main source of cleaning air energy water heater is descaling, so let me take a look at how to clean it.

How to use water heater descaler.

Now take the scale removal of the whole circulation system as an example, and introduce the steps of scale removal:

1.Determine the amount of cooling water stored in the system and calculate the amount of descaler chemicals required.

2.Prepare the material according to the descaler ingredient standard. To use a solid descaler, stir it in a bucket of water to completely dissolve the panicle cracks and then add it to the system.

3.Drain the water from the catchment tray and completely remove the sludge and dirt.

4.Close the drain valve, fill with clean water, turn on the pump, and let the water circulate.

5.Descaler is added during the water cycle. The location where the descaler is applied can be in the sump pan of the cooling tower.

The thermal conductivity of scale is much lower than that of metal, and the thermal conductivity of metal pipes is 6 1000 times that of scale. Hard scale can reduce or even fail the heat conversion rate of water heaters, such as solar energy. This is the reason why the water heater temperature decreases and the amount of water supplied decreases. Scale contains a variety of chemical components, long-term precipitation and accumulation is the increasing number of harmful substances in the water, which may lead to allergies.

As well as slime, microorganisms, and bacteria also generate a lot of harmful substances in the long-term continuous renewal and alternating reaction. It can cause the occurrence of a variety of ** diseases, so this situation needs to be cleaned in time.

1. Some air source water heaters have special sewage Bili nuts under the water tank, and this kind of water heater can directly unscrew the sewage nut to discharge water and drainage. When the water in the tank is almost empty, the scale inside the tank will be carried out. After draining the water, screw the Shixian nut, add some tap water to the water tank, and then unscrew the sewage nut to drain the water, so that the scale in the water tank can be cleaned up several times.

2. Some air source water heaters can discharge water and sewage by adjusting the angle of the safety valve, but Sohui shoots but the water is too slow and the effect is not good;

3. For water heaters without special sewage nuts, it is best to remove the water pipe and safety valve with a safety valve on the right side and discharge the water discharge.

The scale cleaning method is: disassemble the water pipe with the safety valve, so that the water in the water tank can be released, when the water is almost finished, the scale will flow out with the running water, and then add some tap water to the water tank, and then release it, so that you can clean the scale in the water tank several times, and reinstall the water pipe.

The first time to descale is more troublesome, but after a skill, you know how to do the Ming Waiter, in fact, it is also very simple to provoke noisy, it is best to clean the scale regularly according to the local water quality situation and frequency of use.

Buy detergent at the market and come back to clean.

The water tank is generally not cleaned, if there is cleaning, it is simple, depending on what you have to clean, if it is dirt it is a bit troublesome,

There is no need to clean, if you really need to clean, you have to go to the manufacturer or distributor to clean it.
