The present invention relates to a high efficiency hot water heating system, comprising a hearth frame, a heat exchanger and a hot air heat exchanger and a hot water tank group; hot-air heat exchanger located in the furnace comprises a frame and a housing the top of the furnace, the ...
For example, the Energy Efficiency and Conservation Authority in New Zealand (EECA) provides a lot of material on its website to support the uptake of more efficient hot water heating systems, especially solar and hot water heat pumps, which can both attract subsidies for installation (EECA, ...
An energy-efficient hot water heating and air conditioning system, comprising a multi-way valve means is provided as a compressor compressing a high thermal state of the refrigerant vapor, a condenser through multi-way valve means connecting the compressor, the heat exchanger through a multi-way ...
Heating and domestic hot water consume a large amount of energy. The heat supply systems based on fossil fuel burning are of low energy efficiency as well as high air pollution. Air source electricity heat pump (ASAHP) was analyzed to be energy-saving for heating in cold regions. In order...

We invite submissions of novel and original papers to this special issue that extend and advance our scientific/technical understanding of the efficient thermal systems and processes; that included, but not limited to: • Heat transfer • Heat exchangers design and modelling • Water heating ...
The devices are fabricated on a thin optical-adhesive/elastomer with a small mechanical bending strain and water-proofed by optical-adhesive encapsulation in a sandwiched structure. The heat dissipation mechanism of the thin optical-adhesive substrate, thin elastomer-based devices or silicon dioxide ...
Air source heat pump (ASHP) water heater is an energy efficient device implemented for sanitary hot water production. Mathematical models were developed an... M Sikhonza,S Tangwe,M Simon - IEEE 被引量: 0发表: 2018年 HEAT PUMP HEATING SYSTEMS FOR LOW-ENERGY HOUSES IN SWITZERLAND FIELD MEASU...
A new energy efficient process has been developed with solar water heating system for multiend silk reeling, and the energy consumption for cooking and reeling operations is calculated and compared with conventional process. It is found that in conventional process, on an average 570 L and 1000 ...
Unlike other systems, it doesn’t require an additional indoor unit. In normal operation, the heat pump takes care of heating the house. The gas-fired heater is only ever used for hot water or when demand for heat is high, for example on cold winter days. That way, the house is kept...
