The heat store has thermal heat storage and additional melting heat storage. It is especially for heating systems with heat pump operation. A shell-type container in each desired length is laid in the soil and filled with water via two parallel pipes in the form of a coil, the thermal ...
However, to fully exploit their potential, it is necessary to install thermal energy storage units so that their operation is more continuous and economical. In this article are therefore presented different kinds of heat pump systems for heating and cooling of buildings (with a focus on air and...
The present invention relates to a heat pump system for the use of cooling or heating comprising at least one TES (3), wherein the TES comprises thermal energy storage. The TES is placed downstream of a heat exchanger (2) and generally placed upstream of a pressure changing device (4) or...
Technically, you don’t need insulation to use a heat pump. As long as you properly install a big-enough system that suits your local climate, it’ll keep up with your thermostat—even in very cold parts of the world. That said, a super-sized heat pump isn’t always the smartest way...

Thermal and Thermochemical Storage TCES can be operated as a thermally driven chemical heat pump and for heat transformation (upgrading) and cold heat production, and also to store heat ... Y Kato,T Nomura - 《Issues in Environmental Science & Technology》 被引量: 0发表: 2018年 ...
A refrigerant, also known as working fluid, in a heat pump cycle is compressed to liquid state then expanded to a vapour state to absorb and remove heat [20]. Combined solar thermal energy technologies and heat pump into a SAHP system is a promising application offering great potentials to ...
Thermal storage tanks need to store thermal energy for cooling in summer, as opposed to thermal energy for heating in winter. Therefore, this study examines a system comprising a heat pump and a dual latent thermal storage. The dual latent thermal storage tank is equipped with cooling and ...
Heat pump electricity costs grow with a power relationship as the evaporator temperature in the cycle decreases. The thermo-economic study of a solar thermal-assisted heat pump and storage system determines the minimum cost of the coupled system for an evaporator temperature. Through two case studies...
The recovered thermal energy, stored at an elevated temperature in the heat storage, is used as a temporary heat source for the heat pump during discharging mode, which leads to two beneficial applications: 1) to increase COP and reduce compressor power, by reducing the source-sink temperature ...
