Energy and exergy analysis of Hybrid Ground-Coupled Heat Pumps with hot water supply
The energy and exergy efficiencies of a Hybrid Ground-Coupled Heat Pump (HGCHP) system with Domestic Hot Water (DHW) supply are analysed based on experimental study. Comparisons between the HGCHP and conventional DHW systems, i.e., Air Source Heat Pump (ASHP), Electric Heater (ElcH) and Gas-Fired Boiler (GasB), are made with respect to the energy and exergy efficiencies. The results show that the ...

The reference environment: utilising exergy and anergy for buildings
The utilisation of exergy and anergy concepts for low exergy system design extends the potential of performance optimisation of buildings. We propose a new perspective for buildings and their external environment. It recognises exergy as the utilisable potential that maintains comfort inside relative to outside ambient conditions. It considers environmental heat sources as a form of transiting ...

Sludge drying mechanism
The low-temperature heat pump belt drying system is a closed circulation system, and the hot air can be recycled after being heated and dehumidified, without the need for external exhaust gas. In the process of sludge heating and drying, volatile organic compounds will be produced, which will be dissolved in the condensate along with the condensation of water vapor in the exhaust gas, so that the ...

The future of air conditioning in the UK
Over recent years, air conditioning has become much more common in the UK. Even so, there is still concern about the environmental impact of traditional AC units. There is also the indisputable fact that they are currently very expensive to run. The AC industry is working to address both of these issues by leveraging ongoing technological advancements. The history of air conditioning in the UK ...

Future-oriented further developments: wastewater heat utilization plants with a return on investment (ROI) of 2 - 6 years
Sewage is dirty and stinks. Out of sniffing distance – out of mind. Up until the 1980s sewage was taboo and not given the attention it deserves. One cold winter morning in 1988, 23 years ago, Urs Studer stopped beside a steaming manhole cover and wondered how such a source of heat could go untapped. Ever since he has been dedicating himself intensively to the recycling of sewage heat. At ...

Project - Swimming Pool
One of the most appreciated applications of Sferasol is in combination with swimming pools, for water temperature maintenance. In these cases we use the model without water tank SF-A. The sphere is directly connected with the pool heat exchanger, through an external pumping system. The advantage of this solution is the simple network scheme and the aesthetical impact, where you can avoid flat ...

Assessment of exergy efficiency and Sustainability Index of an air?water heat pump
This study is undertaken to predict the second law performance of an air/water heat pump. Through energy and exergy analyses, analytical expressions are derived for the Coefficient of Performance (COP) and Exergy Efficiency (ηexe). The system is analysed to predict how the mass flow rate of R-134a, condensation and evaporation temperatures influence the system performance at various operating ...

COPs, EERs, and SEERs How efficient is your air conditioning system?
Introduction This note discusses performances of air conditioning systems, including heat pumps and chillers. It describes the efficiencies of systems so you can estimate how much energy a system may use. The discussion applies equally to residential, commercial, and industrial systems. When we talk about the size of an air conditioning system (whether by tons of cooling, BTU/h, or kW), we are ...

It’s Time to Rethink Cooling Tower Filtration
ABSTRACTThe dissipation of ambient or process heat in large HVAC systems, manufacturing facilities, power generation plants, refineries, metal mills and forges, chemical plants and food processors is most often accomplished by cooling towers. These simple structures facilitate the transfer of unwanted energy (heat) from a transport liquid (usually water) to the atmosphere. The bane of cooling ...
