Evaluation of Renewable Energy Heat Source System in Small and Medium-sized Restaurant Area

～Example Air Conditioning and Hot Water Supply System by Solar and Geothermal Including Adsorption Refrigerator～

Abstract

This paper presents design and evaluations of hybrid heat source system by sola are geothermal which are one of renewable energy. This research has done as part of the research in the "Honjo Smart Energy Town Project", which has been promoted in Honjo city, Saitama prefecture. The target of the project to realize or propose the effective energy utilization system is including business model. This system is mainly driving by the Geothermal Heat Pump for air conditioning with back-up of adsorption refrigerator which is driven by solar hot water. Solar heating system is used for hot water supply also. By measuring the collection heating value of solar in the summer the maximum calorific value was 1710 MJ per day. The maximum cooling calorific value from geothermal heat pump in the summer was 6700MJ per day. The effect of adsorption refrigerator was confirmed from the operational data.
