This paper investigates the performance of a ground source heat pump that is coupled with a photovoltaic system to provide cooling and heating demands of a zero-energy residential building. Exergy and sustainability analyses have been conducted to evaluate the exergy destruction rate and SI of different compartments of the hybrid system. The effects of monthly thermal load variations on the performance of the hybrid system are investigated. The hybrid system consists of a vertical ground source heat exchanger, rooftop photovoltaic panels, and a heat pump cycle. Exergetic efficiency of the solar-geothermal heat pump system does not exceed 10 percent, and most exergy destruction takes place in photovoltaic panel, condenser, and evaporator.

This research aims to improve the performance of an office building based on a new operation strategy for an evacuated tube solar collector-U-tube ground heat exchanger system. The main problem with the traditional operation strategy is the mismatch between the chiller capacity and the real cooling demand, which leads to operation of the air-conditioner units under low load rates and causes low system efficiency. In order to solve the above problem, we propose a new operation strategy, which controls the unit based on the load distribution of the building. Under this operation mode, the unit operates at full load rate during most operating times. Therefore, it can solve the mismatch between selection and operation and improve energy efficiency.

TRNBuild application was used to design the building model and allowed sample way to change model properties. The developed model could.

Recent Developments in Ground Source Heat Pump System Design, Modeling and Applications

In general, a higher system performance may be achieved by using a GSHP system compared with an air source heat pump system, due to the relatively small temperature variation of the ground compared with the ambient air. The role of indoor distribution systems is to handle building cooling and heating loads by absorbing room heat gains or providing heat to rooms through indoor heat pump units. In this chapter, in-depth discussions regarding GSHP systems are given including the topics of geothermal resources, ground source heat exchangers, indoor distribution systems, heat storage technologies of GSHP systems, as well as their economics and environmental impacts. Additionally, the most updated concepts, designs, and technologies for GSHPs are covered in this chapter.

Study of operational strategies for a hybrid solar-geothermal heat pump system

 Где-то поблизости от Вашингтона, округ Колумбия, сэр. Нуматака высоко поднял брови. - Позвоните, как только узнаете номер. ГЛАВА 72 В погруженной во тьму шифровалке Сьюзан Флетчер осторожно пробиралась к платформе кабинета Стратмора. Только туда ей и оставалось идти в наглухо запертом помещении. Поднявшись по ступенькам, она обнаружила, что дверь в кабинет шефа открыта, поскольку электронный замок без электропитания бесполезен. Она вошла.

Джабба посмотрел на таблицу, что стояла на мониторе, и всплеснул руками. - Здесь около сотни пунктов. Мы не можем вычесть их все одно из другого. - Многие пункты даны не в числовой форме, - подбодрила людей Сьюзан.
