The article provides a review on Heat Pumps (HPs) implementation in Lithuania in compliance with the National Energy Strategy and European policy and encompasses the period 2005–2013 after the Lithuanian integration into the EU. Lithuania has limited quantity of indigenous energy resources and is ...
Fig. 1. Development of temperature levels for compression heat pumps, HP: conventional heat pump, HTHP: high temperature heat pump, VHTHP: very high temperature heat pump, adapted from Peureux and Bobelin [4–8]. This review article assumes 100 °C as a boundary for classifying a HTHP....
Simple though the basic idea may be, the details of how heat pumps work are fascinating. In the name of controlling your home’s temperature, this device can almost seem to break the laws of physics. Heat pumps are also getting better: new models are more efficient and better able to han...
Finally, the review contains proposals for future studies to be carried out so as to contribute to the further development of absorption heat pump technologies. 展开 关键词: Absorption heat pumps Desorber Boiling process Nucleate boiling Convective boiling Boiling heat transfer correlations ...

Like all heat pumps, ground source heat pumps convert mechanical work into heat and supplement this with the pumped (i.e., recycled) heat. The generated thermal energy is therefore the sum the recycled heat and additional heat from electric power consumption. Hence, we define the heat generated...

the pumps are switched off and the mine gradually fills with groundwater until it overflows at the surface via a shaft top, an unplugged exploration borehole, a sough, tunnel or adit. 2. the mine continues to be pumped to prevent it filling with water and threatening other working mines...
Heat pumps are one of the alternative systems with low energy consumption that can be used for heating/cooling [140]. Ground source heat pumps are of two types: vertical type and horizontal type. 2.10. Vertical GROUND SOURCE HEAT PUmp (VGSHP) VGSHP systems offer dual functionality for both ...
Geothermal energy is a renewable and sustainable energy source that can be utilized for district heating and geothermal heat pumps (Hakansson et al., 2013). Generally, most of geothermal systems used the reservoir fluid to carry the heat from the reservoir to the surface in an open loop system...
