Theoretical thermal performance of the air-source heat pumps in Trabzon, Turkey
Abstract
A heat pump raises heat from its surroundings such as air, solar collector, ground water, or waste process heat from a lower temperature level to a higher. A crucial factor in the planning and selection of a heat pump system is the type of intended application. If requirements change from heating to cooling in accordance with the seasons a reversible heat pump can supplement the conventional heating system in winter, or can even replace it. During the summer, the hydraulic system of a heat pump is reversed to supply cooling instead of heat energy. One of the benefits of electric heat pumps is that they can take advantage of the anticipated growth in renewable energy production and provide low-carbon heat generation in the residential and commercial sectors, while also offering potential flexibility on the demand side. In this study, thermal performance of the air-source heat pumps in Trabzon, Turkey was investigated by theoretical with using the SOLSIM simulation program. In this model, an electrically driven air-source heat pump was used for heating a single family building with a floor area of 100 m2. In simulation model, third-order polynomials relating the heat pump’s COP to the outdoor air temperature. Also, economic comparison was made of the heat pump’s performance with Ground source heat pump, oil and natural gas furnace heating systems, using payback-time economic method.
