Before leaving the factory, each unit of the chiller will undergo rigorous testing to ensure that the components of the unit are in good condition and can be operated safely. In use, the following maintenance tips should be remembered.
In its simplest form, there is only one chiller providing chilled water to the building's coils. The chilled water can be cooled by water or air cooling. Without regard to the cooling medium, a single chiller has certain features in common with a combination of multiple chillers.
Chillers are the largest single energy-using component in most facilities and can typically consume more than 50% of the electricity used. In North America and the USA, chillers use approximately 20% of the total electricity generated.
The low pressure fault of chiller is that the compressor inlet pressure is too low, which causes the low pressure protection relay to operate. The normal compressor suction pressure of room temperature chiller should be 0.3~0.45Mpa, and the protection value is set to 0.2Mpa.
