Brian sheridan minitube5/28/2023 In this study, cooling capacity, Coefficient of Performance (COP), compressor power and room temperature were evaluated in three types of trombone coil (6.4 mm coil diameter with a length of 7.9 m, 6.4 mm coil diameter with a length of 5.3 m, and 9.5 mm coil diameter with a length of 5.3 m) with different cooling load variation. The diameter and length of the dummy condenser pipe are intensely affected by ACWH performance. The Air Source Air Conditioning Water Heater (ASACWH) performance as an energy source to heat water in the tank using dummy condenser type of trombone coil with different diameter and pipe length without hot water circulation has been investigated. The system will increase the combined space heating and cooling electricity consumptions annually by 3%, on the other hand, a reduction of 55% of water heater related annual electricity consumption was noted relative to the conventional electric water heater. The outlet water temperature fluctuates in the range of 49.5 ☌ to 55.9 ☌ (while the setpoint temperature was taken at 54 ☌). The best coefficient of performance (COP) was obtained at 20 ☌ and 35% RH from the chosen sets of air conditions. It was concluded that the temperature and humidity of surrounding air produced a considerable impact on the heating capacity of the ASHPWH. Furthermore, the validated models were applied to evaluate the performance of the unit to meet the year-round hot water demand and established its significance with respect to the conventional electric water heater. The research methodology involved, installation of the ASHPWH unit in an Archetype Sustainable House (ASH), reconfiguration of some parts of house plumbing system, build sensors and data acquisition system to collect real-time experimental data, developed and validated TRNSYS models. Therefore, an understanding of energy performance of this types water heaters is critical to justify their use in the Canadian houses. On the other hand, if it is installed in the indoor space (which is the case of this research), the presence of the system in the house affects the house heating and cooling loads. However, the conditions are different in Canada, where outside air temperature is well below the freezing point for several months, and that diminishes the water heating capacity of these systems significantly. ASHPWH has a better performance than the conventional electric water heater if it is installed in a hotter climate. The ultimate joy for me then is to see one of my pictures hanging on the wall of somebody’s home.The performance of a new type of Air Source Heat Pump Water Heater (ASHPWH) has been investigated. For me to put on my hiking boots, load up my camera equipment and head out to places like Connemara, Donegal or Kerry to take pictures, is like being in heaven! To later do some post processing work on the pictures and then get a print on fine art 100% cotton paper from the printer takes me back to the time when I first took a print from the chemical trays in the dark room in Griffith College and further back to when I was that little boy in Donegal collecting the black and white prints from the pharmacy. I am truly blessed to be in living in Ireland, such a beautiful country. Over the years I have ventured into the many photography genres, from portraiture to commercial to fashion but my true love lay with Landscape, Seascapes and Urban. When I graduated I felt that I was now on the path to realising the dream of making images that I had visualised and could now be proud of. This resulted in me beginning on a whole new journey. So in 2002 I went back to college and studied professional photography at Griffith College, Dublin. I could visualise images that I wanted to create but I knew that I was not getting the result that I dreamed of. I found that I had taken my photography as far as I could by myself. I was essentially self-taught, with a little help from reading every photography book and magazine I could lay my hands on. I eventually purchased an SLR and a whole new world opened up for me. My passion for photography continued with me into later life as I progressed from the little plastic camera to more sophisticated models. The memory and excitement of collecting the prints at the local pharmacy stays with me to this day. I have fond memories of taking pictures with a little plastic camera while spending the summer months in my grandmother’s home in Co. My passion for photography began many years ago as a young boy.
