Common problems with high-pressure alarms in high-precision constant temperature and humidity air conditioners

Common problems with high-pressure alarms in high-precision constant temperature and humidity air conditioners

High-precision constant temperature and humidity air conditioner low power supply voltage does not start often due to voltage reduction or phase loss, low power supply voltage, resulting in insufficient output voltage of 24v transformer; 24v AC contactor in condenser cannot work. Specific needs to be tested and determined with a multimeter. If necessary, a power grid voltage stabilizer is equipped.

How to correctly choose high-precision constant temperature and humidity air conditioner for computer room

How to correctly choose high-precision constant temperature and humidity air conditioner for computer room

The high-precision constant temperature and humidity air conditioner for computer rooms has the following characteristics: large air volume, small enthalpy difference, high sensible heat ratio; the heat load of the computer room varies greatly, usually between 10% and 20%; there are various ways of sending and returning air, including upper air supply, lower air supply, upper return air, lower return air, side return air, etc., and the commonly used ones are upper delivery and lower return and lower delivery and upper return; the reliability is high, and the control system and functions of the high-precision constant temperature and humidity air conditioner for computer rooms are much more complete than those of general comfort air conditioners; the reliability of operation throughout the year and all-weather operation.

What is the use of high-precision constant temperature and humidity air conditioning in the inter-row and inter-column computer room?

What is the use of high-precision constant temperature and humidity air conditioning in the inter-row and inter-column computer room?

As the heat dissipation of the servers or communication equipment used in the data center is increasing, the traditional air conditioning and refrigeration methods can no longer meet the equipment's requirements for humidity and temperature. In order to achieve high-efficiency cooling of the equipment and avoid local overheating, cold air must be organized to enter the equipment for heat dissipation. At this time, the use of cold and hot channel isolation or closed cold and hot channels can effectively control the short circuit of cold air and hot air, thereby reducing the cooling effect.
