“…By applying heat recovery, it is possible to use part of the waste heat that would normally be discarded from the system. There are several places in the refrigeration system where heat recovery can be performed, namely: condenser, superheated working gas at the outlet of the compressor, and compressor oil coolers [18]. If waste heat is needed to heat or preheat the water, the most efficient way is to use heat recovery from the refrigerant at the outlet of the compressor.…”

The possibility for utilization of waste heat from processes in the food industry is presented in this paper. The need for reuse of waste heat comes from the fact that energy consumption in industrial companies is uneconomical and that environmental pollution has increased. Therefore, one of the method of reuse of waste heat that is applicable in industrial processes is presented in the paper. Potential primary energy savings is presented by implementing the waste heat recovery in the food factory. The paper presents a simplified solution proposal for installation of heat exchangers with the aim of utilizing the waste heat of the refrigerant. The results showed that by the implementation of simple heat recovery significant annual fuel energy savings can be achieved as well as fuel cost savings.

“…The waste heat from the CHP system drives the absorption cooling system, which in turn, provides cooling for refrigerated display cases, storage areas and the retail space. This concept is known as tri-generation, or combined cooling, heating and power (CCHP) (Sugiartha et al 2009;Fricke 2011). Due to the high initial cost of these systems, the implementation of CCHP and fuel cells has been limited.…”

High initial cost of power plant, limited power capacity of the existing plant and the frequent black out of many districts due to the continuous increase in electrical demands, in addition to the adverse effect of the blackout on hypermarkets, especially on foodstuff such as meat, chicken, etc. strongly encourage the adoption of a regenerating process and the principle of combined heat and power. This work investigates the upgrading of the combined cooling heat and power system and improving the regenerating process adopted in the first design of an existing project. Linking between refrigeration and air-conditioning systems is proposed in scheme-II. A single-effect absorption chiller operating in the range of refrigeration scale (i.e. aqueousammonia refrigeration, not air-conditioning scale, LiBr-H 2 O employed in scheme-I) will be adopted using pressurised hot water recovered from the generators. The chilled water system will be serving three categories in the following order, namely, refrigeration stores, cold stores and air-conditioning units, respectively. The chilled water output of the first category will be the input of the second one. This will enhance the overall system efficiency, reduce the generator load and lessen the fugitive refrigerant emissions, which mainly participate in ozone-depleting potential and global-warming potential. This is in addition to the dramatic reduction in initial and operating cost, which can be estimated to be 50% and 79.6%, respectively.
