LIEBERT air conditioning system：
LIEBER Our global power and thermal management solutions are among the world's most efficient and reliable power and
cooling technologies. The LIEBERT air conditioning system is a system used to control the temperature, humidity, cleanliness, and airflow velocity of indoor air. It enables certain spaces to achieve air with specific temperature, humidity, and air quality levels to meet user and production process requirements, and to improve occupational hygiene and indoor climate conditions.

LIEBERT air conditioning system coolingfunction
Liquid vaporization refrigeration achieves cooling by utilizing the heat absorption effect during liquid vaporization and the heat release effect during condensation. Liquid vaporization forms vapor. When a liquid (refrigerant) is in a sealed container, no other gases exist in the container besides the liquid and the vapor generated by the liquid itself; the liquid and vapor will reach equilibrium at a certain pressure. The vapor at this state is called saturated vapor, the pressure is called saturated pressure, and the temperature is called saturated temperature. At equilibrium, the liquid no longer vaporizes. If a portion of the vapor is removed from the container, the liquid must continue to vaporize to produce more vapor to maintain this equilibrium. Vaporization absorbs heat, known as the latent heat of vaporization. This latent heat comes from the object being cooled, causing it to cool down. To keep this process continuous, vapor must be continuously removed from the container, condensed back into liquid, and returned to the container. If the vapor extracted from the container is directly condensed into liquid, the temperature of the required cooling medium must be lower than the evaporation temperature of the liquid. Since we aim for condensation to occur at ambient temperature, the vapor pressure must be increased to the saturated pressure at ambient temperature.

LIEBERT air conditioning system heatingfunction:
The compressor draws in low-pressure gas and compresses it into high-temperature, high-pressure gas. The high-temperature gas raises the water temperature through a heat exchanger,
while simultaneously condensing into a liquid. The liquid then enters the evaporator for evaporation (during evaporation in the evaporator, a heat exchange medium is also required;
machine models and structures vary depending on the heat exchange medium. Common types include air-cooled and ground-source systems). After passing through the evaporator, the liquid becomes low-pressure, low-temperature gas,
which is again drawn into the compressor for compression. This cycle continues, and the circulating water on the air conditioning side becomes hot water at approximately 45-55 degrees. The hot water is delivered via pipes to rooms requiring heating,
where fan coil units installed in the rooms exchange heat between the hot water and air to achieve heating.

LIEBERT air conditioning systemInstallation basics:

(1) When selecting equipment, choose a larger capacity rather than a smaller one. The idea that air conditioning model size can be reduced due to fewer occupants or fewer rooms in use is incorrect.

(2) The outdoor unit must be placed in a location with good ventilation. Poor ventilation will significantly affect air conditioning performance.

(3) Indoor units should generally not be installed above bathrooms or kitchens. If installation in these locations is unavoidable, a proper return air plan must be developed, ensuring that return air is not drawn from bathrooms or kitchens.

(4) Leave an access panel for the indoor unit to facilitate future maintenance.

(5) Select the air supply outlet position to ensure proper air circulation within the air-conditioned area.

(6) Ensure the air supply outlet dimensions are appropriate; excessively large outlets will affect air conditioning performance.
