Control of Heat Pumps with CO2 Emission Intensity Forecasts

Spatial Analysis of China Provincial-Level CO2 Emission Intensity

This study offers a unique contribution to the literature by investigating the influential factors of energy-related carbon dioxide emission intensity among a panel of 30 provinces in China covering the period 1991-2010. We use novel spatial panel data models to analyze the drivers of energy-related emission intensity, which we posit are characterized by spatial dependence. Our results suggest:...

Province-level Convergence of China CO2 Emission Intensity

Linear programming control of a group of heat pumps∗

For the new Meppel district Nieuwveense landen a hybrid energy concept is developed based on biogas cogeneration. The generated electricity is used to power domestic heat pumps which supply thermal energy for domestic hot water and space heating demand of households. In this paper we investigate scheduling of a group of heat pumps in order to minimize the maximum peak of the total electricity c...

Geothermal Heat Pumps

office building, or school, or replace your heating and cooling system, you may want to consider a geothermal heat pump (GHP) system. GHP systems are also known as GeoExchange, ground-source, or water-source heat pumps (as opposed to air-source heat pumps). Regardless of what you call them, energy-efficient geothermal heat pumps are available today for both residential and commercial building a...

Lubricant Related Problems with Heat-Pumps

Roger Morgan, Lecturer, Brian L. Sutcliffe, Laboratory Technician, Oil is required in refrigeration and heat pump systems for lubrication of the compressor, expansion valve and other moving p~rt7. Ho~ever, the oil is often highly m~sClble wlth the refrigerant, in proportlons which depend on pressure and temperature, as well as oil and refrigerant type. As some of the oil circulates around the s...
