In Layman’s terms

Controlled vs. uncontrolled systems.

In simple terms: Our IP increases the thermal energy of the refrigerant and therefore achieving an increased liquid sub cooling. In essence we are increasing the compressor’s capacity, allowing the variable flow system compressor technology to slow down (or staged shut down), thus achieving substantial energy reductions in energy burned by the system.

Over recent years the ‘old’ single fixed speed compressor (un-controlled) has started to be replaced by more efficient rack systems (staged fixed speed compressors), and more recently variable speed systems (controlled). The single fixed speed system is exactly that, it comes on at one speed and goes off at one speed. Therefore it would run at full speed (and energy consumption), even if the building or refrigerator required only a small load.

Today’s staged and variable technology however provides us with an ‘engine’ with variable speed, therefore we can now reduce the acceleration. We now have an engine (the compressor), which has the ability to slow down in variable or staged modes, simply because the we implement a ‘tail wind’ (the third party heat source i.e. a Solar Thermal Collection System) allowing the engine to take advantage of that tail wind, therefore achieving the original speed (the cooling capacity) without the additional fuel consumption.

 

 

LG thermX

Thermodynamics of ThermX™

The well-known compressor technology is enhanced with a proprietary developed solar thermal collection system. We now have a super advanced compressor system. The “trick” lies in the use of the ideal gas law:

p * V = n * R * T

ThermX™ uses an exclusive patented process, situated between Compressor and Condenser. Utilizing the free available energy from the sun to heat the refrigerant & subsequently reducing the workload of the compressor/s.

As the free energy from the sun heats the refrigerant, it is provided with thermal energy, this in turn raises the internal energy (the sum of all microscopic kinetic and potential energy of the molecules).

The molecules now move with a higher value of kinetic energy, which simply implies each molecule moves with a higher velocity than before. Now the molecules collide with one another and rebound with an increased energy…

…which means a naturally increased mass volume flow, and in an improved Delta T in the condenser and therefore the unequaled cooling and heating process of Solar thermal.

The hotter the sun shines, the more the solar panel takes over the heating of the gas and the more power is saved. The compressor acts now mainly as a pump, providing the necessary cycle flow.

How the heating system works

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 raincloud.
