The present work aimed at evaluating the experimental performance of a gas engine heat pump for hot water supply. In order to achieve this objective, a test facility was developed and experiments were performed over a wide range of ambient air temperature (10.9–25.3 °C), condenser water...

A gas engine heat pump (GEHP) represents one of the most practicable systems which improve the overall energy utilization efficiency and reduce the operating cost for heating and cooling applications. The present work aimed at evaluating the performance of a GEHP for air-conditioning and hot...

Gas engine heat pumps play an important role in energy saving and environment protection in both cooling and heating applications. In the present work, a thermal modelling of the gas engine driven heat pump in cooling mode is performed and system main parameters such as cooling capacity, gas...

The control systems of conventional heat pumps have an input of refrigerant temperature at the evaporator outlet to maintain superheat at proper level. In order to develop a control method that can be used to achieve better indoor thermal comfort and energy efficiency at a low cooling load...

In this paper, we experimentally test the Modigliani-Miller theorem. Applying a general equilibrium approach and not allowing for arbitrage among firms with different capital structure, we are able to address a question fundamental to the valuation of firms: does capital structure affect the...

A model of coalition government formation is presented in which inefficient, non-minimal winning coalitions may form in Nash equilibrium. Predictions for five games are presented and tested experimentally. The experimental data support potential maximization as a refinement of Nash equilibrium....

This paper reports results of an experimental study of uniform and discriminatory auctions of multiple objects in an environment of publicly known common values. We find that the bidding behavior in the uniform case exhibits two clear regularities: agents consistently play weakly dominated...

This paper reports results of an experimental study of uniform multi-unit auctions in an environment of publicly known common values. We find that the bidding behavior exhibits two clear regularities: agents consistently play weakly dominated strategies by overbidding on the first unit and have...

Network formation is frequently modeled using link-formation games and typically present a multiplicity of Nash equilibria. Cooperative refinements —such as strong or coalitional proof Nash equilibria— have been the standard tool used for equilibrium selection in these games. Non-cooperative...

In geographical zones with a continental Mediterranean climate, the convenience of passive systems becomes doubtful, when one takes into account real thermal performance throughout the different seasons of the year. It is assumed that these systems stay shut down during summer thus avoiding...
