much less energy. An energy-smart building starts with thick walls. Special insulation (隔热材料) inside keeps heat inside in winter and keeps heat outside in summer. This saves energy for heating and cooling. Some green buildings don’t need any radiators (散热器) or air conditioning at ...
Considering typical delivery temperatures for heating (45–90 °C for radiators) and cooling (5–15 °C for chilled water) operations, the possible COP values for a GSHP are presented in Fig. 4, wherein the delivery temperatures for heating and cooling are fixed at 65 °C and 5...

In comparison to a heat pump-only approach, the hybrid solution achieved greater energy savings ranging from 24% to 30% in systems with radiators in moderate and cold climates, and approximately 5% to 12% when implementing hybrid systems in newer homes with radiant panels in similar climates [...
“Case 2”) heating terminals. Moreover, the two solutions ensure the inlet of a suitable ventilation rate; however, in the first case, air diffusion take place at h = 6.55 m above the floor, whereas in the second case, fresh air is blown at the floor level (underfloor air distribution...
They have been widely used in energy applications, spacecraft thermal control, electronic device cooling, and commercial radiators [1]. Zhou [2] fabri- cated a plate-type loop heat pipe (LHP) and investigated the effect on the heat transfer performance of the LHP with multilayer metal foams ...
The main air conditioning season is summer, therefore the installation of splits is chosen for the cooling period, while boilers and radiators have been selected for residential use. Each housing unit consists of an entrance-living room, a cooking area, a bathroom and a bedroom. The building ...
