INTEGRATED ENERGY SYSTEMS
The system is capable of reducing energy usage in centres by more than 50%.
The combination of plant efficiencies and the recycling of energy in the building allows centres to move their budgets back towards the black. A situation that has been out of reach for centres until now.
What is COP?
You will have seen the energy rating stars on household appliances. These are rating the appliance with regard to how many times greater than 1 that appliance is for energy consumption. The more stars it has, the more efficient the appliance is. We use a more specific measure for energy efficiency with thermal systems and it is called the Coefficient of Performance: the COP.
This is a measure of how much useful thermal work is done by a machine for a unit of electrical energy 1kW of power. An electric water heater that you see in most houses has a COP of 1. A gas water heater will have a COP of about 0.85. But an integrated heat pump for heating water can have a COP of more than 11, as you add the energy from the hot and cold that is produced. This means that for every 1kW of electricity that you use, the system will produce a combined 11kW of heating and cooling. The compressor is not ‘making’ the energy: it is transferring the energy from the air surrounding the building to be used somewhere else, such as the pool or a weights room.
