In case of textile mill, it requires central air conditioning plant which requires chilled water and hot water for steam generation and heating purpose, while in food industries, refrigeration required for product preservation and hot water required for cleaning, sterilization or process heating. Many food industries, textiles industries, hotels require both refrigeration and water heating. Refrigeration technology is expected to develop technologies which are cheap and using refrigerant other than CFC. Emphasis is given to save energy and to protect the environment. In todays era, refrigeration industry is passing through evolutionary changes. Experimental results show that R134a has good performance than R22 and performance of R407 is in same manner as R22. In which water flow rate is varied and test was conducted in three different modes by using R22 and its alternative refrigerants like R134a, R407C, R410A in existing system without replacing any parts of the system. For research work water cooled condenser and evaporator is used. And even due to simultaneous operation the requirement individual equipment is no more so it saved the first cost of equipment. The main advantage of the simultaneous is to carry out heating and cooling in dual mode, by which fossil fuel can be saved by minimize the use of the energy due to simultaneous operation. This research paper presents a vapour compression refrigeration (VCR) system for simultaneous heating and cooling utilities for different purpose in industries, hotels.
