A refrigerant is an element in the form of liquid or gas. A specific area in the refrigeration succession cools down using the refrigerant. The process seizes heat from space and then releases it into another space. This is the act of a refrigerant. Refrigerants in refrigerating systems (air conditioners) absorb fluid and release heat. Apart from this, Thermodynamic phenomena of phase change are the process also used by refrigerants. This helps the liquid to convert to gas and gas into a liquid. The process of refrigerant starts in the evaporator component of the system. The refrigerant liquid will absorb heat and also change to vapour under low pressure. The vapour travels to the compressor component of the system. The compressor pressure and temperature increases. The release of heat from the vapour happens at this stage. The release of heat happens in the condenser component. The refrigerant then changes back to liquid form. It travels back to the evaporator. Repetition of the process happens again and again with the same liquid.

65% BUILDING ENERGY DIGUNAKAN UNTUK VENTILATING & AIR CONDITIONING. Kenyataan tersebut membuat pengelola gedung dituntut untuk melakukan terobosan terobosan teknis untuk menurunkan biaya Opeasional dari Perangkat Air Conditioning. Hal yang menyebabkan kita ABAI unutk melakukan penghematan energy di VAC adalah:

HVAC Optimization in a full scale typically reduces energy usage and costs by 20 to 40 and a really enery efficiant model will make use of all available energy. Some method like Supercooling can manage the HVAC Systems electricity and able to reduce the energy usage by up to 25%.

This heat rejection is accomplished through the natural process of evaporation that takes place when air and water is brought into direct contact in the cooling tower. The evaporation is most efficient when the maximum water surface area is exposed to the maximum flow of air in the longest possible period of time. Cooling towers are designed in two different configurations, CounterFlow and CrossFlow. The specific configuration indicates the direction of the air flow in relation to the water flow.

For over a century scientists have known that certain frequencies of light have a devastating effect on microbial life. We now know that exposure to ultraviolet light in the range of 254 NM (UV-C band) disrupts the DNA of micro-organisms thus preventing them from reproducing, thereby effectively killing them.

Real-world energy savings obtainable from load vs. lift Variable speed drives (VSDs) can cut a chiller’s annual energy use by up to 30 percent while maintaining operating reliably over a wide range of condition. This is accomplished in two ways:
