THERMODYNAMIC BOX
History
This range of energy saving technologies has been developed since the start of Freezer technology some 100 years ago.
What is it?
The Synagia Solar Thermodynamic system comprises two components – the Thermodynamic Panel and the heat pump.
Officially the system is classified by the Government as a “Solar Assisted Heat Pump”.
This is the Microgeneration Certification Scheme (MCS) definition – “Solar Assisted Heat Pump (SAHP) is a system which absorbs atmospheric heat (e.g. via an external absorber) and turns this into useful heat energy for domestic hot water and heating. An external absorber (the Thermodynamic panel) acts as an evaporator and utilises the heat in the atmosphere as well as direct solar radiation. Generally, the absorber will be placed externally however in some cases may be placed internally (in the loft is usually ideal). “ In layman’s terms, this is a high-quality freezer working in reverse.
What does it do?
It takes “heat” out of the atmosphere (outside or in the loft), and compresses it into high quality useful heat at 60⁰ C. The refrigerant pumped from the Heat Pump to the outside situated absorber (Thermodynamic Panel) is at -20⁰C. This is very cold, and immediately is warmed up by the ambient temperature of the surrounding air. In England and Wales, the average 24-hour ambient temperature in winter is +4⁰C, so the “Delta T” (temperature difference -20 to +4) is 24⁰C. This difference “heats” the very cold refrigerant which when compressed heats up to 60⁰C and will produce sufficient hot water to give you baths and showers throughout the whole day and on the larger systems – heat your central heating. The Synagia Solar Thermodynamic system will work efficiently with outside temperatures down to -15⁰C. It continues to work with temperatures below that, but not efficiently. The Synagia Thermodynamic system retrofit is connected to the existing cylinder to heat up your potable water. It is important to have the volume of your cylinder sized to suit your bathing habits, so that there is always sufficient volume of hot water available. Once your hot water cylinder is heated up to the target temperature of 60⁰C, the system goes into standby-mode until you draw more hot water and the temperature in the cylinder reduces.
HOT WATER CYLINDER
Synagia Solar Cylinder
Our Synagia Solar Cylinder is a highly insulated hot water cylinder in a smart “white goods” type enclosure to ensure minimal heat loss. It combines our innovation solar assisted heat pump technology with a 130, 150, 200, 250, 300 or 500 liter cylinder.
SYNAGIA COLLECTOR PANEL
Collector Panel
Made of roll-bond aluminium, it is highly durable (no glass or glycol) and absorbs energy from ambient air, sunlight, wind & rain. Very light and easy to install. Normally fitted in the loft or to an outside wall. Can be fitted to any aspect. Panel is silent in operation. Length 1.7m Width 0.8m Depth 25mm (single) 100mm (double) Weight 7kg
How it works
The aluminum panel circulates the refrigerated liquid where energy is absorbed from the ambient air. This transforms the liquid into a gas, which carries the heat energy to the Thermodynamic Box. The Thermodynamic Box compresses the gas which increases the temperature. The spent gas reverts back to a liquid which flows back into the panel, allowing the process to repeat. Simultaneously, a water pump pulls cold water from the cylinder into the Thermodynamic Box. This works as a heat exchanger which returns hot water to the cylinder. This flow continues until the water in the cylinder reaches 55°C. Once this is achieved the system goes into standby.
