This 33 MW water-source heat pump delivers space heating for a plant cultivation greenhouse facility. A local body of water is used as the heat source, and the system consists of 4 ammonia heat pumps operating in parallel.

Star’s site maintenance includes weekly site visits, quarterly oil analysis and vibration analysis every two months – these checks allow engineers to spot early signs of wear and tear and prevent deterioration of plant performance.

Twice-yearly thermal imaging helps identify any heat loss, leaks or blockages and ensures that temperatures are kept within specified tolerances. Performed annually, gas detection calibration safeguards workers by checking refrigerant leak detection systems, and temperature probe calibration ensures accurate temperature readings.

Finally, performing annual compressor oil filter replacements prevents contamination and extends the lubricant’s lifespan, which reduces wear on the compressor.

These checks not only lead to optimal system performance, but also help to prevent costly system failure and regulatory non-compliance.
