Page 22: Water System Installation
Water system installation Water quality requirements Water in the water system must be softened to prevent scale in the heat exchanger and affecting the heat exchanger performance. Water not softened can also cause scale in the water pipes and cause the water resistance to increase. This affects the water flow and the performance of the water pump. - Page 23 Installation illustration for the water system of a single unit: EXPANSION WATER TANK REFILL DRAIN WATER TANK HEATER REFILL DRAIN COOLING TOWER REFILL DRAIN Installation illustration for water system of multi-unit combination: AIR DISCHARGE REFILL DN20 - - - FULL COOLING TOWE REFILL DRAINAGE...

- Page 25 The switchover between water-cooled chilled water and water-source hot water modes can be achieved easily by the opening and closing of valves in the water system to meet the annual demand for cooling or heating. The cold and heat source can be waste heat, geothermal source, water source and others. The operation is more efficient and more ecofriendly.
- Page 26 * Determining the diameter of pipes in the air conditioning system The pipe diameter is determined based on the following: = water flow m v = water speed m/s The water speed should be determined by the recommendations in the first table and design the water pipe diameters accordingly, or you can determine the water pipe diameter based on water flow in the second table.
