WSK Krakow Ltd. as the only Polish heating pumps producer has been qualified for GreenEvo project.
VATRA series heating pumps has been selected as one of most innovative Polish environmental friendly technologies.
GreenEvo project is realized by Polish Ministry of Environment, its goal is to identify and promote best polish environmental technologies.
The heat pump is heating and cooling device, in principle forcing transformation of thermal energy
from lower to higher temperature level. Energy transformation occurs through energy consumption
from the center of lower temperature and putting it to a resort with higher temperature.
According to the principle of thermodynamics heat flow occurs from body with higher temperature
to body with lower temperature. The heat pump reverses this process with the participation of
additional energy supplied from outside, used to drive the refrigeration compressor.
Heat pump may also be used as a cooling device. In this case the pump collects heat from high resort
and transfers it to lower heat resort. The heat transformation in heating pump is done by using the overheat and condensation
characteristic of refrigerant circulating in the system which performs thermodynamic cycle.
Produced heat is used to heat water in the installation circulation system (optional: air stream in installation
circulation system). Geothermal heat pump is used as a heating-cooling equipment in: homes, industrial
applications (greenhouses, cold rooms, swimming pools), public buildings.
Pump production technology requires precise calculations of functional elements (such as heat exchangers, parameters of the compressor,
parameters of expansion valve), implementation of appropriate manufacturing technology and proper design in order to
minimize device vibrations, ensure device integrity, and optimal control unit to control pump processes.
