Air Source Heat Pump Should Be Evacuated During Installation

What should we pay attention to in the air source heat pump installation?

Under the leadership of the low-carbon economy, the wind of clean heating is blowing, making air energy heat pumps shine in the ventilation industry. With the advantages of cleanliness, high efficiency, energy saving, safety and reliability, air source heat pumps have quickly occupied the market share in the industry, winning the favor of the market. Faced with such large-scale heating equipment, every aspect from selection to purchase, installation, and maintenance is important. People often pay the most attention to the product itself, but they easily overlook the installation problems that follow, thinking that a good product can be used casually. In fact, this is not the case. Just imagine that after you have surveyed the market many times and finally found a brand that you are satisfied with, if you encounter some errors during installation, it will lead to failure and it will be a pity.

It is necessary to vacuum air source heat pump installation

Why choose air source heat pump installation? Air source heat pump installation is to absorb low-temperature heat from the air and convert it to achieve cooling, heating, and hot water services. However, the moisture in the air is one of the biggest enemies of air energy heat pumps. Therefore, when more moisture enters the main engine, it will cause serious paralysis and failure of the unit. Therefore, in the installation of air source heat pumps, remember to vacuum. What will happen if these gases are not vented?

When installing air source heat pumps without vacuuming, these gases will flow to the system as the main engine runs, resulting in the following situations:

The lubricating oil of the compressor in the air energy heat pump main engine will react with the moisture in the air to generate water-soluble acids, which will corrode the copper tube and affect the service life of the product; after the copper is corroded, copper ions will freely flow into the refrigerant, causing "copper plating" and damaging the compressor; non-condensing gases in the air will cause the exhaust temperature of the compressor in the air energy heat pump main engine to rise, and the heating efficiency will be greatly reduced, while the power consumption will increase, and the customer will feel that it is consuming more energy, without the energy-saving effect promised at the beginning. When the exhaust temperature is greater than 110°C, a fault occurs, and this fault will not be evident for a long time, thus increasing unnecessary after-sales problems; moreover, when the exhaust temperature is too high, the lubricating oil in the compressor will carbonize, and these carbonized substances will easily cause blockage when passing through the expansion valve or capillary, causing the refrigerant to be unable to flow, ultimately causing the unit to fail.

Through the above understanding, I believe everyone understands the necessity of vacuuming during the installation of split-type air source heat pumps. If you need professional air source heat pump installation services, please feel free to consult us.
