M-Thermal of fers Mono and Split type products. Mono’s hydronic components are located within the outdoor unit for easy installation.
Split type has separate outdoor unit and hydronic box for more flexibility. Both Mono and Split type products achieve Erp A++ rate
energy efficiency grade. So they make significant contribution to the limiting the impact on the environment.
As the refrigerant passes through the expansion valve and expands, its temperature and pressure both drop. Refrigerant R410a does not freeze even though the temperature is very low.
With the temperature of the refrigerant being lower than the ambient temperature, heat passes from the air ﬂowing over the air side heat exchanger to the refrigerant and the refrigerant evaporates.
When the refrigerant vapor passes through the compressor its pressure increases and its temperature rises above that of the water in M-Thermal’s hydronic system.
As the hot vapor refrigerant passes through the water side heat exchanger it heats the water in the hydronic system, which is then pumped indoors to the space heating terminals and domestic hot water tank. The refrigerant cools and condenses and is then ready to return to the expansion valve to start the cycle again.
