Discussion of heating in hot summer and cold winter zone

Heating in this area should be designed by using adequate technologies with sufficient consideration of the local characters of sociaty and nature, and the health and comfort of indoor environment and the energy utilization efficiency of heating in this area should be superior to those in the north with central heating. The traditional heating mode by fuel combustion should be replaced with heat pump techniques, taking heat from natural environment. The heating system mode, central or decentralized, depends on heat source as well as society and environment resources; decentralized heating is better with air source and centralized heating is better with ground or water source. Various heating modes should be positively developed. For a project, an appropriate heating mode should be determined based on its own conditions.
