HEAT PUMPING TECHNOLOGIES IN ASIA AND THE PACIFIC: AN OVERVIEW


The current overall picture of “heat pumping technologies” in Asia and the Pacific is briefly reviewed
in this paper. Of the various facets of heat pumping technologies in Asia and the Pacific, the most
outstanding feature of this region is the increasing demand for air conditioning of residential and
commercial buildings. The rapid proliferation of air conditioning has been the main cause for pushing up
power demand, causing shortage in power supply and deterioration of power load factor.
As the measure for power load leveling, cool storage system and thermally driven cooling system
have extensively been used for air conditioning of buildings, shaping a unique market structure in this
region. On the other hand, heat pumping technologies for heating purposes have vigorously been exploited
in this region for space heating, tap water heating and industrial process heating.
Considering the huge market potential for air conditioning and heating, still left unexplored in this
region, and the resulting future impact on global environment, development of advanced energy efficient
and environmentally friendly technologies is of vital importance for the sustainable development in the
foreseeable future.
