Why did the PC liquid cooling segment redefine terms that have been used in HVAC for over 100 years, with worse definitions? A real ‘closed loop system’ is a chilled water loop with no evaporative cooling tower. A real ‘open loop system’ is a chilled water loop with an evaporative cooling tower. The loop is open to the atmosphere at the cooling tower. What the computer cooling industry calls a ‘closed loop system’ (a refrigerant based cooler that comes with precharged lines) normal people call them ‘a closed loop system with pre-charged linesets’. Split A/C units often come with precharged linesets that you just plug in to the condenser and evaporator (air handler) without having to charge the system with refrigerant. Now, for some on-topic commentary. If you put together what I will call a closed loop system consisting of tubing, water blocks, a pump, and a remote condenser, it could potentially be almost silent. The only things that make noise are the fans and pumps and those can be located anywhere you want with enough tubing. If you’re trying to dissipate 1kW of heat, it’ll be a lot easier with a heat pump than with air alone, liquid-to-air heat exchangers are quite amazing.
