Maintenance Manual Magnetic bearing chillers with the microtech ? Page 3: Introduction Introduction The air-cooled mini chillers form part of a complete integrated water hydronic system with the chiller water fan coil units. Page 4 Schematic diagram of the basic close hydronic system: Expansion tank Heat Pump Heat SOURCE LOAD Distribution system In the mini chiller, the source will comprise of the refrigeration circuit, i. Page 5 If both chilled water and hot water are required in the system, a mini chiller with a reverse cycle operation will be used. The unit will have an additional 4-way valve and accumulator for this purpose.

It is by such integration of components of the hydronic system that the mini chiller becomes compact. Page 6: Chiller Mounting Section 1: Chiller Mounting Care must be taken to locate the air-cooled chiller at the proper place. Ensure sufficient clearance around the unit to allow proper air flow and to facilitate access for maintenance. Location of the units must also prevent short-circuiting of the discharge air.

Do not block any air passage in and out of the units. Page 7 Such brackets must have sufficient strength to carry the weight of the chiller unit. These brackets must also allow clearance for removal of service panels for maintenance purposes. Page 9 For the A-series type of mini chiller, the inter-connecting pipes between the two compartments are the refrigerant pipes. For the B-series type, there is a water pipe in between the two compartments. Therefore, the detached installation of the A-series mini chillers is very similar to the installation of a split type air-conditioning unit. Use as few bends as possible in the pipe run.

Each bend will cause extra pressure drop and reduces the capacity of the system. Do not use more than 10 bends. For both A and B- series chillers, locating the hydraulic kit at a far distance will also mean having a longer water pipe length. Page 11: Water Pipe Circuit Section 2: Water Pipe Circuit We have seen that the mini chiller has an integrated buffer storage tank, expansion tank and water pump together as one unit. Page 13 Parallel Direct Return Horizontal installation Fan coil unit Vertical installation The basis for the design is “First In – First Out”. In this system, the length of supply and return piping for each fan coil is unequal. This will affect the water flow rate through each individual load.

Proper balancing is required to provide adequate water flow rate for each fan coil. Page 14 Parallel Reverse Return Horizontal Installation Fan coil unit Vertical Installation The basis for the design is “First In – Last Out”. In this installation, the supply and return water pipes or of nearly equal lengths. Thus, it seldom requires balancing of water flow rate for individual fan coil unit. If required, this balancing will be easier. Page 15 Parallel Reverse Return Header, Direct Supply Rise This is a variation of both the direct and reverse return systems, whereby it is not feasible to have a full reverse return piping. Instead, only the return header is in reverse, whereas the supply to the individual fan coils are in direct configuration.
