Evaporator Latent Heat

Heat is absorbed into the refrigerant from the water system in the shell and tube evaporator. The refrigerant boils from a cold liquid into a vapour.

Condenser Heat Rejection

Heat added in the evaporator and heat added from the compressor, is rejected into the water tower system in the shell and tube condenser. The refrigerant condenses into a liquid from a vapour.

Chiller Faults

A lot of faults can be remedied with the stock of parts and materials that the engineer carries in his car. Some materials can be sourced from local suppliers, others can be delivered same day. We will go a long way to improve the condition of your chiller. This is just part of the way we deal with the customer- you! If we can keep you happy- that makes us happy!

Case Study of Chiller Service

On a site in Northampton, a chiller looked like it was short of gas, but to a discerning eye: it was malfunctioning- the EEV had failed. The mechanical part of the electronic expansion valve had jammed up causing the chiller to trip out. A relatively easy job as it was just a straight swap. The chiller was pumped down and valved off. The EEV driver was okay. The valve clamped on to the body with a knife edge seal. This particular valve is prone to failure- the other 3 systems across both 0.5 mw chillers has had one fail too.

Evaporator Freeze-Up

The worst issue for a chiller is an evaporator freeze-up.

What Happens when the Safeties Fail?

The compressor carries on running. The evaporator turns into a solid block of ice. Ice has a larger size than water, so as it expands, it buckles then bursts the evaporator. The compressor still carries on running. Refrigerant leaks into the water system until the pressure in the fridge system and the water system equalise. Then, water is sucked into the fridge system. It gets sucked into the compressor and round to the condenser. Compressors cannot compress a liquid, so a compressor smash-up occurs.

How do we Service the Chiller?

The compressor or compressors need to be re-built. The evaporator needs to be stripped down and refurbished. The system needs to be dehydrated which takes several months. On a smaller chiller, the costs outweigh a replacement- so the chiller is ruined.

What can be done to Prevent this?

Regular chiller maintenance is essential to stop this happening and to prevent other small problems becoming big ones. If, however, your chiller does need a repair- we at Maximus Chillers will get your chiller running better than when it came out of the factory!
