Zeroth Energy System
This innovative system has been designed in conjunction with leading industry developers, recognising the need for a new, highly efficient communal solution for residential apartments.
The Zeroth Energy System takes a compact, in-apartment water source heat pump, low temperature (or ambient) energy loop and central plant to offer heating, hot water and comfort cooling to apartment developments as a commercially advantageous solution.
In-apartment heat pumps provide efficient HVAC services
The advantages of heat pumps are available across multiple applications but are best placed in well-insulated buildings where the heat pump effects on furthering the building efficiency can be realised. Apartments can benefit from a system where all the heating, cooling and hot water supply is provided by an in-apartment heat pump.
A heat pump may also be integrated with a specific function, such as mechanical ventilation with heat recovery, to maximise the energy cycle. The system can work together with another energy source, such a traditional combustion boiler but also integrate with a fully renewable source like solar PV system. In addition to the primary function of a heat pump to deliver HVAC services, the excess energy generated can be discharged into thermal storage systems, or buffer tanks, to provide a more efficient on-demand service for heating and cooling without the need to short cycle the system when the demand is low. This creates a more efficient and sustainable communal energy network.
The Zeroth unit is a water source heat pump, which connects to a low temperature (or ambient) water loop designed at 25°C. This loop is kept within operating temperatures by a central plant:
