How to determine whether the air can water heater needs to add refrigerant?

in the air can water heater, cold media plays the important role of transport of heat, referred to as the 'blood' of air can water heater. In the most began to install air can water heater installation personnel usually one-time add refrigerant, if installation and reliable, do not need to add refrigerant within the next 10 years.

if in use process suddenly found not good heating unit, it is likely to be the machine failure refrigerant leakage. Unit, of course, no heating is not short of refrigerant, but his lack of refrigerant can't necessarily lead to heat. User if found that air can water heater unit has the following situation should be short of refrigerant: under normal circumstances unit in open after an hour, about 20 ℃, the temperature will rise if not reach the temperature may be short of refrigerant; Can also go to a test machine outside the outlet, the outlet temperature is low, the blown out if it is temperature, may be added refrigerant; Under the boot after half an hour, if the host found no condensed water discharged, can also be short of refrigerant; Refrigerant leakage can also lead to low pressure drop, resulting in the evaporator frosting tendency, may appear unreasonable frost phenomenon; Because of refrigerant and oil is mutually soluble, if the host junction and valve has a very obvious phenomenon of greasy, is a good chance that refrigerant leakage, the so-called 'refrigerant leakage will spill, the oil will leak refrigerant' is the meaning.

if you have to determine is short of refrigerant, it must be done in a timely manner. Before adding fluoride to ensure the system has no leakage, and then pumping air into vacuum state, the system with a dedicated vacuum equipment of the air inside smoke clean; After good vacuum, find air can water heater low pressure to join points, most of the join points are located on the back to the port of the compressor Find pressure into the point after ready to add refrigerant and pressure gauge, electronic scale, and send to the end of the gauge to low pressure to join points, the other end to cold media bottle, before receiving the unit system to put the gas in the pipeline dry; According to the specifications of the unit, filling the right amount of refrigerant. Specific to how much, please refer to the nameplate parameters. Had better use electronic said to add, not add pressure gauge doesn't look right; Charging is completed, restart the host observe the host running situation, if you find any of these conditions don't solve, will add some cold media.

of course, this is just a simple add methods, if you really want to meet of failure of air unit can't heating, it is better to contact the factory service department to check, maintenance. Air to the installation, maintenance is relatively complex, need to understand master the technology. Now can air industry competition is intense, manufacturer is good and bad are intermingled, many enterprises and dealers in sales after the product's devotion to after-sales without too much, lead to machine can't get the maintenance in time after failure. So, when the choose and buy air can, try to choose and buy some new en tai, mitra, such as the professional brand, or the comprehensive such as midea, gree, haier electrical home appliances brands, product quality is guaranteed, and after-sale do very in position.

It isn't just about being on air conditioner capacitor anymore–it's about maximizing the potential of the platform of manufacturing.

Review Hangzhou E cool refrigeration Co.,Ltd's progress at regular intervals, so we can continue with the strategies that work well and change or eliminate the ones that don't give the results we are looking for.
