The coupling of these solar collectors with a heat pump can enhance low levels of solar radiation, allowing at the same time heat pump COPs higher than using outside air as cold source. In fact at an operating temperature only 5 °C higher than the outside air, not only frosting/defrostin...
A CO2 heat pump water heater (HPWH) can provide hot water with a relatively high COP and consume significantly less energy than all electric or gas water heaters. This study reviews and analyses the existing CO2 HPWHs both in industrial and residential sectors, where the low-temperature and ...
Keep your New York home comfortable year-round with an energy saving, environmentally friendly cold climate heat pump. Cold climate heat pumps, also known as ductless mini-split systems, provide a renewable energy option for your heating and air conditioning needs....
This study presents the development and evaluation of a novel partially open-loop heat pump dryer with a unit-room (HPDU). The unit-room was designed to enable the ambient air to be mixed with the return air, thereby reducing the influence of the ambient air on the system performance, whi...
An improved cold climate air-source heat pump comprising at least a primary compressor, a booster compressor, a first heat exchanger associated with an indoor environment and a second heat exchanger associated with an outdoor environment and with one heat exchanger acting as an evaporator and the ...
Mini-splits in cold climates? Yes we can! Three years ago, I installed a ¾-ton Fujitsu modelair-source mini-splitheat pump to heat my historic 1790 cape home here in Northfield, Massachusetts. It has been a great success. During the winter of 2010–2011, the heater for my 1,500 ...
latent thermal energy storage; phase change material (PCM); performance indicators; scaling up; experimental evaluation; heat pump1. Introduction The heating and cooling sector in buildings is crucial for the achievement of climate change mitigation targets worldwide [1,2]. Accordingly, the problem ...
Guiyin Fang, in Renewable and Sustainable Energy Reviews, 2019 2.4 Photovoltaic–thermal integrated heat pump systems Heat pumps can transfer thermal energy from a source at a lower temperature to a hotter sink by using mechanical energy. The coefficient of performance (COP) of a heat pump is ...
