Study on the Solar Energy Heat Pump Space Heating System in the Agricultural and Pastoral Areas in Inner Mongolia

Abstract

An investigation on the space heating conditions in the agricultural and pastoral areas in Baotou city in Inner Mongolia has been carried out to study the heating energy resources and devices. It is found that using fossil fuels directly is the main heating form, which is inefficient, costly, and may cause higher energy consumption, poor indoor air quality, and serious environmental contamination. The solar energy heat pump space heating system is proposed for the specific use in the agricultural and pastoral area on the basis of the previous studies. The principle, control strategy, and operation modes of the system are studied and analyzed. In order to further validate the feasibility of this system, the economic benefits, social benefits, and environmental benefits of the solar energy heat pump space heating system are investigated and analyzed. Using this solar energy space heating system, about 15 tons CO2 emission per year could be avoided for a 100 m2 house in the agricultural and pastoral area, as well as a great amount of other noxious gases.
