Micro Combined Heat and Power (µchp)

Principle

The principle is that a gas or oil fuelled engine drives a generator that produces electricity.

The heat from the engine block, oil cooler and exhaust, which would normally be wasted is absorbed by coolant ( usually water) through a high efficiency heat exchanger. This energy, stored as hot water, is then usable directly for:

In general, the production of 1 kilowatt of power creates 2 kilowatts of usable heat energy.

Solutions

All Davmark™ solutions normally consist of a co-generation unit powered by natural gas or diesel, a heat storage system and an advanced computer management package.

Accessories, such as heat pumps and / or boilers, can be added to become an integral part of the complete control system. The Power solution is an open platform that can be implemented into any new or existing installation.

Improve Efficiency by 100%

The extremely high efficiency of a µCHP systems is dramatically superseding ordinary energy technology.

By comparison, traditional electricity production has an efficiency of only 30 - 40%. Thus, the Combined Heat and Power solution can reduce energy bills by 40 - 60%, or increase efficiency by more than 100% - a considerable improvement.

Furthermore, the Davmark™ solution will reduce future investments in the energy infrastructure. By decentralising energy production, the need for new, regional transmission systems for heating and power will be diminished and transmission losses, a substantial cost factor in any centralised energy supply system, will be greatly reduced or become non-existent.

Simple Installation

Installation is simple and fast, occupying only minimal space. A large µchp system, will typically require only 2 square meters (18 square feet) of floor space. It is capable of producing 17 kilowatts of electricity and 24 kilowatts of heat.

The system can arrive pre-engineered and fully automated. It normally consists of:

Accessories such as heat pumps and/or gas/oil fired boilers can be added to become an integral part of the complete control system.

Commissioning

Commissioning is carried out by our qualified contract engineers to ensure a quick and effective installation.

The Davmark™ solution can be designed to be an open platform that can be implemented into any new or existing installation. Particular care is taken to bring the system controls into the e-build, intelligent building management system.
