Pompes à chaleur air/eau

POMPE A CHALEUR Air/Eau

Les pompes à chaleur sont considérées comme une solution de chauffage écologique conçue pour être économe en énergie tout en respectant l'environnement. Grâce à l'utilisation de fluides caloporteurs ultra-efficaces et des derniers composants de haute technologie, les pompes à chaleur Euro Plumbing réduisent efficacement la consommation d'énergie même dans les conditions les plus froides.
Types de pompe à chaleur.
Air to air which is known as `air conditioning’ common in many buildings already. This not a system offered by Euro Pluming.
Air to water heat pump which draws heat from outside air and transfers heat to a fluid that can be pumped to underfloor systems or radiators or even hot water storage. This is the cheaper heat pump option to install for hydronic heating. A convenient external location is sited for placement of the heat pump where it can be connected to power and pipework.
Air to water heat pumps are available in varying power options in both standard heat for underfloor heating or high temp for radiators and DHW supply.
Heat pumps are available in a range of sizes to suit required heating output and in two temperature ranges. Standard heat pumps temperature of approximately 450 which is designed for underfloor heating where a constant low temperature is required to radiate wary temp heat pumps that put out a temperature of 65° are designed for radiator systems and heating domestic hot water. Choice of heat t depend on maximum temperature requirement.

Heat pumps work by moving a transfer fluid around a closed circuit. The circuit is made up of:

A.    A compressor – fluid arriving from the evaporator in low pressure is taken high pressure and absorbs a quantity of heat in this process.

B.    A condenser—fluid arriving from the compressor
releases heat to the environment.

C.    An expansion valve – fluid passing through the    heat source expansion valve is partly transformed and cools in the process

D.    An evaporator – coldness is transferred to the environment and heat is absorbed to start process again,  If a heat pump is run in a reverse cycle the condenser becomes the   evaporator and evaporator is the condenser and cooling is achieved rather than heating. For underfloor or fan forced air movement, this gives option of cooling for summer temperatures.

Geo Thermal Heat Pump Water to Water

Water to water also known as ground source or geothermal Heat pump. The system uses an external loop in the ground to collect warmth or transfer coldness. Due to collection of heat from underground where the temperature is a more stable to to 14° depending on soil type, this is the most efficient system with expected energy gains to be 4 to 1 or 400% to input power. For setting up system either ground has to be excavated for laying coils of pipe in a trench or over a layer and then covered again or bores have to be drilled for vertical cores to be dropped into. Even though system is called ground source or geothermal, the heat source is actually solar with the suns energy absorbed into surface soil and carried down by water movement. For this reason efficiencies are not as good in free draining earth structures or directly under paved zones.
