1. Brine circulates in a collector coil and draws low temperature energy from the ground, air, bedrock or water.
2. At the heat exchanger (evaporator) the tepid brine in the collector coil meets the ice cold refrigerant in the heat pump which is then heated a few degrees and converted to gas.
3. In the compressor, the pressure is increased thereby raising the temperature of the refrigerant. The heat that is then generated is transferred via a heat exchanger (condenser) to your home's heating system.
4. Via the condenser, the refrigerant releases the heat to the heating system of your home. In connection with this the refrigerant is cooled.
5. The refrigerant circulates and an expansion valve lowers the pressure and the refrigerant becomes cold again. The process begins again when the refrigerant meets the tepid brine from the collector coil.
The brine is a mixture that cannot freeze, for example alcohol or glycol
Modern environmentally sound refrigerants are used e.g. hydrocarbons and carbon dioxide.
At Syntegra Consulting we are able to undertake Building services design consultancy & Energy consultancy commissions throughout the UK. Our Building Services consultants are experienced and specialist areas of expertise. We have represented the International IBG at executive board level and also lead well respected blue chip companies at senior management level.
Growing environmental concerns, the Carbon Reduction Commitment (CRC) and the steady rise in fuel prices have made energy efficiency a key driver for many organisations to consider for sustainable building services design solutions. Enforcement of the Kyoto Agreement and the introduction of policies such as the climate change levy, carbon emissions trading, Part L of the building regulations, and the EPBD have put focus on the energy conservation, sustainable development, and renewable energy sources
Syntegra Building Services design & energy consultants can work direct to private clients, or as part of a corporate multi-disciplinary design team, offering expert strategic advice on infrastructure design(electrical services, public health services, mechanical services), energy procurement, alternative renewable technology options, and meeting sustainability goals. Our approach and design solutions helps to reduce operating costs without impacting on clients' strategic objective aspirations. Key areas offered are as follows:
Mechanical & Electrical Services Consultancy
Public Health Consultancy
Specialist Lighting Design
Low Zero Carbon (LZC) feasibility studies
Intelligent Building Consultancy
Carbon Reduction Commitment (CRC) Consultancy
Energy Grant advice
For recently constructed projects, we can also carry out a range of post-occupancy energy audits, utility tariff reviews, surveys, and monitoring studies that assess performance and identify wastage. We evaluate operational conditions and put in place procedures to ensure plant and BMS and other service/systems are maintained and set up to maximise energy efficiency, including whole-life cycle commissioning and risk-based maintenance strategies.
