Geothermal heat pump application for space cooling in Kamphaengphet, Thailand

Scaling in Geothermal Heat Pump Systems

INTRODUCTION Water quality is a frequently overlooked issue in the application of geothermal heat pump (GHP) systems. When considered at all, is often viewed as a problem unique to open loop systems. In residential open loop applications water is supplied directly to the heat pump’s refrigerant-to-water heat exchanger. If the water has a tendency to be scale forming, fouling of the heat exchang...

Modeling Convective Heat Transfer in a Geothermal Heat Pump System

Energy efficiency model for small/medium geothermal heat pump systems

Heating application efficiency is a crucial point for saving energy and reducing greenhouse gas emissions. Today, EU legal framework conditions clearly define how heating systems should perform, how buildings should be designed in an energy efficient manner and how renewable energy sources should be used. Using heat pumps (HP) as an alternative “Renewable Energy System” could be one solution fo...

However, GHPs often have higher first costs than conventional systems making short-term economics unattractive. This disadvantage can be magnified in commercial buildings, many o...

Optimization Of A Heat Pump For Satellite Cooling

In recent years the heat fluxes that must be removed from terrestrial electrical systems have been steadily increasing. The same increase in electrical component heat flux can also be seen in satellite and aerospace applications. As a result, it has proven necessary to develop heat pump systems that can operate in low-gravity environments with high reliability and efficiency to cool electrical ...
