电热泵用于蔬菜温室供热的经济性分析

现代化蔬菜温室是我国都市农业发展中的一个重要组成部分，目前这类温室的冬季加热均以燃煤方式为主．伴随着越加严重的城市环境污染，温室供热系统也面临着改造问题，需要引入清洁供热方式，热泵供热是其中的一种．本文以上海地区现代化蔬菜温室为研究对象，分析了蔬菜温室中使用电热泵供热的运行成本，并与燃煤供热方式进行了对比．就热泵供热系统在温室中的应用前景及可行性、经济性进行了分析，为热泵在温室供热系统中的应用提供了可参考依据．

ECONOMICAL ANALYSIS OF HEAT PUMP APPLIED IN HEATING SYSTEMS OF VEGETABLE GREENHOUSES

Modern vegetable greenhouses, in which coal-burning boilers are the main way to heat in winter, have been one of the essential parts of the urban agriculture development. With more and more serious problems of pollution in urban areas, the heating systems in greenhouses face the challenge of renovation. Clean heating systems, for example heat pump, are needed. In this paper, the heating systems in modern vegetable greenhouses in Shanghai are studied. The running cost of heat pump in the vegetable greenhouses is analyzed and furthermore is contrasted with that of the coal-burning boiler. The application and economics prospect of the heat pump is analyzed. All of above aim at improving the performance of greenhouse heating systems in winter.
