What is the solution of air conditioning not cooling

There are many reasons why the air conditioner is not cooling. For example, if the air conditioner refrigerant is insufficient, you can find a professional to add snow; secondly, it may be caused by the error of the air conditioner installation, such as the ventilation pipe is too long. It is recommended to shorten the length of the ventilation pipe; A lot of dust stains accumulate on the radiator and cause no cooling. It is recommended to clean the air conditioner.

Quick look Small chillers summer maintenance tips

Quick look! Small chillers summer maintenance tips The high-temperature summer is a frequent season of safety production accidents, which affects the cooling effect of small chillers to a certain extent. Therefore, in order to reduce the equipment failure time and the losses it brings, we must always pay attention to the impact of high temperature on the small chiller equipment, and do a good job in the summer maintenance of the small chiller.

Application advantages and working process analysis of air energy heat pump

Air energy heat pump is to use the energy in the air to generate heat energy. It can provide 24 hours a day with large water volume, high water pressure and constant temperature to provide the family with different hot water, cooling and heating needs, and at the same time can meet the above requirements with the least energy consumption.<img src="{{media url=&quot;Application_advantages_and_working_process_analysis_of_air_energy_heat_pump.jpg&quot;}}" alt="" />
