CO2 AND PRIMARY ENERGY CONSUMPTION REDUCTIONS POTENTIAL WITH HEAT PUMP TECHNOLOGIES IN THE FOOD AND BEVERAGE SECTOR


Heat pumps have become increasingly important in the world as a technology to contribute to CO2 reductions. So far, heat pumps have been widely used in building airconditioning and are expected to spread to industrial fields in the future. In business categories such as food and beverage manufacturing factories, since the operating temperature level is relatively low, the introduction of heat pumps into this field is considered to be easy. In this analysis, CO2 reductions potential in 11 countries by applying heat pumps
in the food and beverage sector was estimated for the purpose of determining the CO2 reductions effect produced by introducing heat pumps. On the assumption that an electric
drive compressor heat pump is used, heat demands below 100 ? out of steam from boiler are selected as a heat pump applicable area. As a result of this estimation, it has been
concluded that the emissions of 47 million tons of CO2 per year can be reduced and this amounts to about 1.4% of CO2 emissions from fuel combustion in the industrial sector in
countries surveyed.
