· System introduction
As CE compliance required, for the safety of heat pump system, the R290 gas volume indoors is not allowed to exceed 150g due to the flammable and combustible characteristic for this gas. We add three safety devices to prevent leakages to indoors mechanically and make sure 100% gas safety.
The whole logic is:
When the refrigerant leakage occurs inside the plate heat exchanger, the Pressure release valve will discharge the leaked refrigerant, through Refrigerant discharge pipe. The Gas seperator will give the signal feedback to main control board and the anti-leakage logic will be activated immediately---power the electric two-way valve on and switch the water circuit ; compressor and water pump will turn off; fan motor keeps running to speed up the emission of leaked refrigerant, in order to prevent the leaked refrigerant from entering indoor (leakage amount should be less than 150g) and make sure the safety of the system.
· Key components for system safety
Pressure release valve
When the pressure in the water system is greater than 2.5bar, quickly drain the gas and water from the system to reduce the pressure.
Gas separator
Exhaust the gas when it is detected inside the water system.
One-way valve
Prevent refrigerant or water from flowing back into the water system in the indoor side.
