The article compares traditional technologies of cooling of milk and heating of technological water and shows efficiency of technology of the combined production of heat and cold on the basis of heat pump use. The technical and economic calculations of efficiency of heat pump use is presented. Through the use of heat pump of "liquid - liquid" type system allows to maintain high precision temperature control of technological processes, thereby improving the quality of dairy products and reduce production costsenheat pumpsrenewable sources of energydairy productionArticle
