To achieve the ultimate available efficiencies, ThermX panels should only ever be installed on systems correctly specified for the cooling or heating load requirements, and only on systems with the ability to unload. We can NOW fit Thermx to fixed speed compressors find out more :
Staged or rack systems
Screw type systems
Digital scroll systems
VRV or VRF systems
” Thermx assisted cooling is only compatible when fitted on systems with a variable capacity ability “.
Why solar thermal works
Understanding the solar thermal technology is about understanding the most important components of the modern-day variable or modulating system controls, the change of state from vapour to liquid, along with the importance of the kinetic energy changes in the refrigerant. Variable refrigerant systems have changed a number of the fundamentals in the refrigerant process over recent years. The solar thermal addition to this process further improves the effectiveness of these systems by creating an improved efficiency via the two crucial components in the cooling and refrigeration cycle; the heat exchanger and the metering device.
The sensible thermal energy added by the solar thermal array replaces an element of the thermal energy normally generated by the compressor in the compression process. The compressor is the most energy hungry component in the whole process, the addition of solar thermal energy into the process can have credible positive impact on the efficiency of this component.
The combination of reducing the compressors workload, while maintaining the refrigerant temperatures required to deliver an efficient Delta T (ΔT), achieves a more rapid change of state, a more efficient sub cooling and in the end, an enhanced cooling capacity.
“The sun was always the problem; today however it can be utilised as the solution”.
Thermx For Heating
In heating mode the system works in almost the same way, but now the flow changes compared to the cooling mode. The additional free heating of the refrigerant in the solar panel allows the compressor to reduce its load, and therefore, its power consumption. Dependent on sun levels, COP figures (heating capacity vs power consumption) of over 8 are possible!
Again the more the sun shines, the more the solar panel takes over the compressing of the gas and the more power is saved, as the compressor now acts mainly as a pump providing the necessary cycle flow.
Due to the ultra UV absorbent design and glass vacuum tubing, the ambient external temperature has little if any impact on the temperature of the gas. The only natural element driving this positive process is the free energy provided by the sun’s rays.
The system is also fitted with the innovative Solar Bypass Valve. This allows the gas to bypass the panel in heating mode, when the sun is non-existent. i.e. night-time and heavy rain-cloud.
