A rational energy use of factories is one of the priorities of modernization of domestic economy aimed at introduction of energy saving technologies. According to the data of the International Institute of Refrigeration (IIR) power consumption of enterprises should be reduced by 30-50% during from 2000 to 2020 period. The energy auditing that is energy inspection is a mechanism of estimation of power efficiency of refrigeration facilities. The paper cites the structure of heat balances of cold chambers of meat processing factories. When drawing up heat balances and estimating energy intensity of products processing and storage the indices of relations between a specific cold consumption at different outdoor air temperatures and an analogical index at annual average temperature should be taken into account. The correlation dependences of cold specific consumption required for meat refrigeration and freezing depending on the utilization factor of chambers are given. It is shown that the power saving potential is generally defined by the increase of the utilization factor of chambers. It was established that when the utilization of the chambers was lower 70% the excessive consumption of cold increased abruptly and was about 4% at an average for each 10% decrease of utilization of chambers.
