The Application Of Ground-Coupled Heat Pump And Energy Storage System For Residential Building

Ground-Coupled Heat Pump technique is becoming more and more focus of the world's attention as a HVAC technique of energy saving and environment protection. But it abroad application is restricted for it costly first cost and the question about the need of consider load balance. Therefore, in order to solve the two problems of the Ground-Coupled Heat Pump technique, and promote its development and application. This paper launched the optimization of the Ground-Coupled Heat Pump technique.This paper pays attention to the analysis and research of the principle and performance and characteristic about the Ground-Coupled Heat Pump technique. Compared Ground-Coupled Heat Pump system with some heating and Air-conditioning systems about the composing of the investment, received the reason of the high first cost of the Ground-Coupled Heat Pump system; at the same time, analyze the influence of the load imbalance between winter and summer to the Ground-Coupled Heat Pump system, in order to solve the two problems of the Ground-Coupled Heat Pump technique, realize the optimization of the Ground-Coupled Heat Pump system.In order to realize the optimization of the Ground-Coupled Heat Pump system, this paper introduces ice storage air-conditioning system. And analyze the principle, running model, performance and characteristic, economical benefit of the ice storage air-conditioning system. The characteristic that it can enhance the running rate of the refrigerate set, cut down the mainframe, decrease the cost of consumer for the different charge standard between peak and low power, provides technical support to the optimization of the Ground-Coupled Heat Pump system.Based on the research of the Ground-Coupled Heat Pump technique and ice storage technique, this paper put forward a project for the optimization of the Ground-Coupled Heat Pump system. Join the ice storage technique to the Ground-Coupled Heat Pump system, realize the virtues offset to each other, form the Ground-coupled Heat Pump and Energy storage technique that give priority to Ground-coupled Heat Pump. This Paper analyze the principle, load calculate, running model, running strategy, control strategy of the new system. And together with the example of project, analyze the economical benefit, the applicability in the areas that the load in summer bigger than the load in winter to the system. Result show: compared with Ground-Coupled Heat Pump system, Ground-coupled Heat Pump and Energy storage system not only cut down first cost, good running stability in the areas that the load in summer bigger than the load in winter, but also has higher running rate, decrease running cost. Therefore, this optimize project is feasible. This investigate provides supports to the utility of the terrestrial heat and the application in the area where the load is unbalance in a year about the Ground-Coupled Heat Pump.
