Low Carbon Technology
Energy production is now cleaner than ever before. See Fig.1 the breakdown of how our energy is generated from 1996 to 2017.
Renewables capacity has seen a significant increase, with installed capacity increasing by nearly 18 times the capacity in 1996 to 40.6 GW in 2017
FIGURE 1
The amount of C02 generated for every kWh of energy used has now more than halved thanks to the grid energy becoming far more clean.
This now means that ASHP technology has becoming one of the most carbon efficient way of heating commercial properties and hot water production.
How do ASHP Work?
DVM Hydro Unit HE (High Efficiency) - Hot water up to 50°C
• Heat pump & Heat recovery (simultaneous cooling & heating) system
• Air-to-water heating and cooling
• Consist of DVM outdoor units and hydro unit
• Indoor units are compatible for air-to-air solution
• Compatible with under floor heating and fan coil units
• Water temperature up to 50°C
• Integrated control system
DVM Hydro Unit HT (High Temperature) - Hot water up to 80°C
• Heat pump & Heat recovery (simultaneous cooling & heating) system
• Air-to-water heating
• Consist of DVM outdoor units and hydro unit
• Indoor units are compatible for air-to-air solution
• Compatible with under floor heating and fan coil units
• Water temperature up to 80°C
• Integrated control system
ASHP Example
Hydro Units to be located in a plant room with Domestic Hot Water storage tanks.
These will be connected to the Air Sourced Heat Pump on the roof.
Hydro units can provide hot water up to 80°c
Hot Water up to 50°c
The average efficiency throughout one year. 1kW electricity consumed produces 4.5kW heating capacity.
Hot Water up to 80°c
The average efficiency throughout one year. 1kW electricity consumed produces 3kW heating capacity.
The footprint of both products are 330 x 518mm. The height of the HE model is 660mm and the height of the HT model is 1210mm
The Air Sourced Heat Pump must be installed outside in order to absorb energy from the environment so it can be used to heat the hot water for the building
This product can also be connected to Air Conditioning products in the office space for both cooling and heating. During the summer the heat removed from the office space can be used to heat the hot water saving electrical consumption for the building.
The ASHP on the roof is connected to the hydro unit in the plant room by copper pipework. The dimensions of this pipework are very small so it can be hidden very easily.
The Hydro unit and the Water tank are connected to then provide hot water to the rest of the building for water use in toilets, showers or even radiators if preferred.
Ideally we would make the hot water as a by product of the cooling process of the office space to further save the energy consumption of the building.
