Sub-hourly simulation of residential ground coupled heat pump systems

numerical simulation of a horizontal ground-coupled heat pump

this study represents effect of four variables in performance of a heat-pump in two cities of tehran and rasht. a computer program has been developed, simulating a certain heat pump acting in different environments with different refrigerants in heating season. the analysis is based on a homogeneous model. effect of different refrigerants, depth of the buried heat exchangers and moisture conten...

Heat Transfer Modeling of the Ground Heat Exchangers for the Ground-Coupled Heat Pump Systems

Ground-coupled heat pump (GCHP) systems have been gaining increasing popularity for space air conditioning in buildings due to their reduced energy and maintenance costs. The efficiency of GCHP systems is inherently higher than that of the traditional options because it utilizes the ground which maintains a relatively stable temperature all the year round as a heat source/sink. Compared with tr...

Simulation and Optimization of Ground Source Heat Pump Systems

Performance assessment of heat pump systems in non-residential buildings by means of dedicated simulation models

A possibility of increasing interest for reducing the energy consumption in office and health care buildings consist in better exploiting the potential of the heat pump technology. This can be done by recovering heat at the condenser when the chiller is used to produce cold (simultaneous heating and cooling demands) or by using the chiller in heat pump mode (non-simultaneous heating and cooling...

Advanced simulation methods for heat pump systems

Within the use of renewable energies in buildings several dynamic influences and interactions have to be regarded. For example, the performance of heat pump systems depends sensitively on weather or geological effects as well as on building and user behaviour. An energetic optimization requires an intelligent coupling and control of all components of the building services installation, the buil...
