The commissioning of a piece of equipment is a standard procedure across the industry. However, with incorrect commissioning, customers can find themselves at risk of unexpected equipment failure and downtime leading to large costs.
Pete Mills, Commercial Technical Operations Manager at Bosch Commercial and Industrial outlines the process of VRF commissioning and what Bosch offers.
What is involved?
The next step is a vacuum test which is done at 0.5 Torr for an hour to dehydrate the system and ensure it is free of any dirt or moisture. The engineer then adds a specific amount of refrigerant into the system, which is likely to vary between manufacturers.
The final step is to test the equipment – the power is switched on for a minimum of 12 hours so the outdoor unit can heat up. From there, the cooling and heating are tested which is essential for ensuring the system is ready for the customer to use.
Most manufacturers use a standard process which consists of a regular pressure test followed by a vacuum. Although it is not a legislative requirement, Bosch engineers champion using a triple evacuation system whereby there is a pressure test followed by a vacuum test and this process is repeated three times. This system is the best way to be certain that any dirt or moisture which may have found its way into the system has been removed and delivers far better results than a standard vacuum process.
Free VRF commissioning
VRF is a new product to Bosch and one that a lot of our customers wouldn't have necessarily seen or used before, so we want to offer our customers a relaxed approach to the commissioning process and the Bosch brand. The company is an entirely new entrant into the VRF market. The commissioning process can vary from one manufacturer's VRF system to the next, so we're keen to eliminate any potential inconsistencies by having one of our engineer's commission the system at no extra cost.
The service we offer also includes on-site training which consists of hints and tips about how best to benefit from the installation. When we come out to a site, we teach the customer how to commission and test a VRF system to ensure it is set up correctly and to make the client feel more at ease with our equipment.
Ultimately, through a thorough commissioning process and on-site training, engineers and maintenance staff can ensure their VRF system will make a real difference to the comfort and efficiency levels within their building.
