Air conditioning is one of the most important, expensive and highly desirable services available to businesses today. It is the one system that can boost productivity in any office or factory by removing heat and humidity, thus creating a pleasant environment for employees. Temperature must be maintained within narrow limits (22 - 25 ˚C) to carry out optimum economic production of goods; while some systems need cooling only, others require more than this. Refrigeration is required to maintain different foodstuffs at temperatures below ambient conditions of summer climate. In most cases, refrigeration is used to maintain temperature of products at low values during transportation and storage, so to extend the shelf life of good. For supermarkets and hotels, temperature can be higher than 25 ˚C for storage of food products. Air conditioning is an important source of cooling which makes up about 9% of all cooling – this amount makes air conditioners the 2nd largest energy user during the summer months. Air conditioners are necessary to ensure comfort for humans irrespective of time or place. Apart from that, they also act as an effective way for controlling pests and many other functions that are required by the society. Air conditioning is the practice of controlling temperature, humidity, and air movement within building spaces. Commercial control of environmental conditions is important for many reasons, including comfort and safety. Energy savings also reduce operating expenses and improve productivity. Indoor pollution can be drastically lowered by investing in good ventilation systems. Many commercial activities require specific temperature ranges to be maintained because human safety or product quality may otherwise suffer or decline. Lighting levels can be altered depending on if the space is occupied or unoccupied to reduce energy costs while still ensuring a safe environment. An air conditioning system must be designed, selected, installed, operated and maintained properly to ensure effective performance. It should also be cost-effective. The anticipated economic advantages of an installed system must outweigh the initial investment costs over its entire life cycle to ensure the success of the operation. It is therefore necessary for anyone concerned with energy conservation to have a basic understanding of the principles involved in the operation of an air conditioning system.
There are two types of refrigeration cycles, namely The concepts behind these cycles are fairly straightforward and easy to understand. They include: Chilled water : This is water that has been cooled below its normal saturation temperature at atmospheric pressure. Saturation temperature refers to the temperature at which air can hold or "saturate" a maximum amount of water vapor. : This is water that has been cooled below its normal saturation temperature at atmospheric pressure. Saturation temperature refers to the temperature at which air can hold or "saturate" a maximum amount of water vapor. Evaporator : A device for converting a liquid into a gas, called evaporation, by cooling below its boiling point. It is usually made out of copper tubes within an Air Handling Unit (AHU). : A device for converting a liquid into a gas, called evaporation, by cooling below its boiling point.
