홈페이지논문 초록 (Abstract)
Heat pumps, as a process recirculating environmental heat back into useful heat production, fit the environmental requirements of prese nt global policy. They are very useful tools to reduce the need of fos sil fuels in space heating and cooling. The government of the Republic of Korea has promoted the distribution of heat pump systems that appl y geothermal energy, and has adopted regulation to prevent the use o f low efficiency heat pump units. Only heat pump units certified by the government can be used in ground source heat pump (GSHP) systems. Certified heat pump units in the Republic of Korea were analyzed and discussed in this paper. All certified products had cooling capa cities less than 280 kW (80 RT). Most of the cooling COPs (Coefficient of Performance)s were found to be superior to heating COPs for GSH P units in the Republic of Korea. To save energy, correspond to environ mental regulations and reduce the installation cost of applying GSHP s ystems, it is suggested that the certification standard concerning unde rground circulation flow rate should be revised. In addition, there is a need forthe revision of the certification standards to include flo or heating in order to be able to apply GSHP systems for a variet y of purposes. (C) 2012 Elsevier Ltd.
