Using The Favourable Environmental Conditions

In areas with a dry climate in winter and dry-bulb temperature (air) and the wet-bulb thermometer (water), the temperature is very low, especially at night. In winter, cooling towers may be able to give temperature 8 12C. plate heat exchangers can be used to transfer the heat load directly to the tower, bypassing the chillers and off the compressors or absorption machines. This system is used in very cold countries to prevent ice formation in cooling towers.

The design of the New Air-conditioning Systems installation for 100% Fresh Air (in Winter)and air conditioning systems with centralized air conditioning, fresh air and exhaust air ducts can be provided with dampers (and blowers, if necessary) to mix fresh air or to use 100% fresh, filtered air, depending on environmental conditions. These systems must also provide the means to exhaust the stale, warm air. Such conditioning system can be installed with enthalpy sensors and motor damper, to maximize the use of ambient air is fresh.

Normal energy consumption of air conditioning may be relatively less in winter, but even this can be avoided if the system design includes the use of favorable environmental conditions.

Fresh air system can be easily upgraded in most air-conditioning systems with the ventilation of the room.

Use Of Geothermal Heat Pumps

The near constant temperature on earth may be used to cool the air for cooling comfort. This method is suitable only during the dry season. It may not be suitable at high relative humidity. This technique was practically demonstrated at the Energy research Institute, Gurgaon...
