The imperative of work – this is the fourth instalment in a five-part series.

At a Frigair Expo 2025 Sairac presentation, , a consulting engineer with , emphasised that irrespective of ejectors, designing for higher wherever possible offers drastic, year-round savings. This directly aligns with the core principle of across the . A higher evaporating temperature translates to a higher suction pressure, leading to a smaller pressure differential for the compressor to overcome.

The imperative of work – this is the third instalment in a five-part series.

At a Frigair Expo 2025 Sairac presentation, , a consulting engineer with ThermoLogica, said that one of the most contentious, yet impactful, optimisation strategies is . This process, regardless of its implementation method, leverages the effect of . By pre-cooling the ambient air entering the gas cooler, it effectively reduces the dry bulb temperature from, for instance, 32°C to 26°C (with 60% effectiveness).
