Investigation of Heat Pump Operation Strategies with Thermal Storage in Heating Conditions

Investigation of Heat Pump Operation Strategies with Thermal Storage in Heating Conditions

A heat pump with thermal storage system is a system that operates a heat pump during night-time using inexpensive electricity; during this time, the generated thermal energy is stored in a thermal storage tank. The stored thermal energy is used by the heat pump during daytime. Based on a model of a dual latent heat storage tank and a heat pump, this study conducts control simulations using both...

Life-Cycle Assessment of an Innovative Ground-Source Heat Pump System with Upstream Thermal Storage

An innovative space-conditioning system is proposed and a life-cycle assessment (LCA) is presented. The layout is obtained starting from a ground-source heat pump system (GSHP) and includes upstream thermal storage (TS). A prototype of the system, implemented following this new approach, is currently in use for space heating and cooling of an industrial building. As a result of the TS designed ...

Modelling of Commercial Absorption Heat Pump with Integral Storage

The thermo-chemical accumulator (TCA) is a closed absorption batch process that uses a working pair, not only in the liquid, vapor and solution phases but also with solid sorbent, so called triple state operation. It was patented in 2000 (Olsson et al., 2000). Since then the TCA process has been developed in a relatively short space of time by the Swedish company ClimateWell via five generation...
