Abstract
The goal of this research is to evaluate the efficacy and practicality of installing a ground source heat pump (GSHP) with an air source heat pump (ASHP) in a residential setting. The results of this comparison were obtained by monitoring each of the systems in two almost identical residences in Perth, Western Australia. There is an open-loop groundwater system in the previous home. Each residence has one family whose air conditioning system has its own set of operational needs. The cooling capacity supplied and coefficient of performance (COP) as a function of seasonal changes in ambient temperatures were determined using data gathered from both residences over a two-year period. For both heating and cooling, the GSHP system COP was found to be greater than that of the ASHP system. Furthermore, these two performance measures were independent of ambient circumstances in the former, but they exhibit a noticeable ambient dependent trend in the latter. The GSHP had an average COP of 4.0 for heating, regardless of external conditions, while the ASHP COP ranged from 2.0 to 3.0. Conversely, the GSHP had an average COP of 3.2 for cooling, whereas the ASHP COP ranged from 1.4 to 2.9. It is found that GSHPs result in significant operational cost reductions and a significant decrease in greenhouse gas emissions when a borewell is part of a home.
Highlights
Based on the Australian energy regulator [1], electricity markets in the twenty-first century exhibited a rising tendency to 210 TWh until around 2008-9, and a small decline to 195.7 town to date
The findings reveal that the major energy savings for ground source heat pump (GSHP) systems are significantly dependent on geography, with reductions of up to 33.6% in colder locations and 23.5% in warmer places
This can be attributed to actual heating and cooling loads caused by resident usage patterns, which are determined by the number of people living in the home, the number of zones that are used, and interior sources such as refrigerators, microwaves, gas stoves, television sets, computers, and so on
Summary
Based on the Australian energy regulator [1], electricity markets in the twenty-first century exhibited a rising tendency to 210 TWh until around 2008-9, and a small decline to 195.7 town to date. Consumer reaction to rising power rates, the introduction of energy-efficient equipment, and smarter house design are all possible causes for the drop. GSHPs utilise the subterranean environment's consistent temperature as a heat source for heating and a heat sink for cooling, insulating heating and cooling equipment from diurnal and seasonal temperature changes [4]. This feature should be considered in conjunction with a reduction in the amount of energy required to operate GSHPs as well as making them more environmentally friendly [5].
