Description
India, being a warm tropical country, most of the refrigeration and HVAC applications involve cooling of air, water, other fluids or products. Heating is used only for a very small period in winter in the northern parts of the country and in places at high altitudes.Refrigeration and Air-conditioning accounts for a significant portion of the energy consumption in many manufacturing industries (like chemicals, pharmaceuticals, dairy, food etc.), agricultural & horticultural sectors (mainly cold stores) and commercial buildings (like hotels, hospitals, offices, airports, theatres, auditoria, multiplexes, data processing centers, telecom switching exchanges etc).
Refrigeration and air conditioning systems cover a wide variety of cooling applications, using both standard and custom-made equipments.
Some commonly used applications are process cooling by chilled water or brine, ice plants, cold stores, freeze drying, air-conditioning systems etc.
Comfort air-conditioning generally implies cooling of room air to about 24°C and relative humidity in the range of 50% to 60%. Industrial process air conditioning and precision air conditioning may require temperatures ranging from 18°C to 24°C with relative humidity values ranging from 10% to 60%.
This manual highlights some issues related to energy efficiency and energy conservation in refrigeration and air conditioning, along with some emerging innovative techniques to eliminate or minimize conventional refrigeration and air conditioning.
