Home air energy water heater repair and maintenance tips

Through the previous articles to introduce the maintenance and maintenance of air energy water heaters, many readers have been paying attention to the information. Below I will briefly introduce the basic maintenance plan for the air energy water heater home machine and some agent engineering machines.

The service life of air energy water heaters is generally more than 8 years. Because the air energy heat pump water heater is a highly automated equipment, the unit status check is carried out regularly during use, and the unit is subjected to long-term effective maintenance and maintenance, and the unit's operational reliability and service life will be unexpectedly improved.

First of all, it should be checked frequently whether the wiring of the power supply and electrical system of the unit is firm, whether the electrical components are abnormal, and should be repaired and replaced in time.

Secondly, it should also be checked frequently whether the water system hydration, water tank safety valve, liquid level controller and exhaust device work properly, so as to avoid the air circulation into the system and reduce the water circulation, thus affecting the unit's heating capacity and unit operation reliability. At the same time, it is not negligible to check whether the water pump and the waterway valve are working properly, and whether the water pipe and the water pipe joint leak.

In addition, it is necessary to check the working condition of each component of the unit frequently, check whether the pipeline joints and the inflation valve in the machine are oily, and ensure that the refrigerant of the unit is not leaked. When the actual water outlet temperature of the air source heat pump water heater is inconsistent with the display value of the unit control panel, it can be detected whether the temperature sensing device is in good contact. In this way, frequent inspections of the product not only ensure that it works efficiently and effectively, but also greatly extend the service life of the product.

Air energy water heater maintenance knowledge

First of all, the water filter installed outside the hot water machine should be cleaned regularly to ensure that the water quality in the system is clean to avoid damage to the main unit due to dirty filter. At the same time, do not pile up debris around the unit to avoid blocking the air inlet and outlet. The unit should also be kept clean and dry around the unit to ensure good ventilation.

In addition, when cleaning the main condenser, it is recommended to clean the condenser with hot phosphoric acid solution of 50 °C-60 °C and 15% concentration every two years. Start the main unit with circulating water pump for 3 hours, and finally wash it with tap water for 3 times. . Do not wash the condenser with a corrosive cleaning solution. If the downtime is long, the water in the unit piping should be drained, the power supply should be cut off, and the protective cover should be placed. When running again, check the system thoroughly before starting up. Moreover, after the water tank is used for a period of time (generally 3 months, depending on the local water quality), the scale needs to be cleaned. It should also be noted that silicon phosphorus crystals can also be used in areas with high water hardness, and soft water machines can be used to soften water.

Sandwich panels

Sandwich panels that with environmental protection materials is easy and fast in installation. The advantage of sandwich panels are light weight, waterproofing, heat insulation, sound absorption, fire resistance, high strength, durable and so on.

Sandwich panels can be install easily,save time,labor and money.

Application: sandwich panels are widely used as roof and wall material, for Steel Structure, warehouse,

poultry house,hangar,car parking,gym,commercial and civilian facilities, shelters,etc.
