Commercial HVAC
Stands for heating, ventilation and air conditioning. This system provides heating and cooling to commercial buildings.
Ground source heat pumps take heat from the ground, raise its temperature and use the energy to heat your property. Ground source heat pumps operate on the same refrigeration cycle principles as a domestic fridge but use the cycle in reverse to generate spatial heating and domestic hot water. The pumps can also be used to provide spatial cooling either using a passive circuit to meet low-level cooling demands or using an active circuit where cooling demands are higher. Both active and passive modes can act to partially replenish the ground array and, if both heating and cooling modes are utilised, the total annualised seasonal performance factors can be very high. This can deliver excellent fuel savings and significant carbon emissions reductions.
The advantage of using a ground source heat pump is its efficiency. For every kWh of electricity used to power the heat pump, about three or four kWh of energy is extracted from the ground. This ratio of heat supplied to the building and the electrical energy consumed is called the Coefficient of Performance (CoP). In the simplest form, think of it as buy one get three free!
The installation will typically consist of a heat pump, ground collector array to absorb energy from the ground, a manifold and manifold pit for joining it all together, circulation pumps to move the energy around the system, various automatic and manual valves, an expansion vessel, buffer tanks to store the energy, a hot water cylinder for heating domestic hot water and a weather compensated control system to make it all work
