SYSTEM DESIGN GUIDE HEAT SOURCE 2) Cooling tower a) Types of cooling tower Types of cooling towers The cooling towers presently used include the open type cooling tower, open type cooling tower + heat exchanger, closed type cooling tower, and air-cooled type cooling Closed type tower.
  • Page 69 8. SYSTEM DESIGN GUIDE HEAT SOURCE 3) Auxiliary heat source and heat storage tank When the heating load is larger than the cooling load, the circulation water temperature lowers in accordance with the heat balance of the system. It should be heated by the auxiliary heat source in order to keep the inlet water tempera- ture within the operating range (10°C [50°F] or more) of the water heat source CITY MULTI.

  • Page 71 8. SYSTEM DESIGN GUIDE HEAT SOURCE b) Heat storage tank Heat storage tank can be classified by types into the open type heat storage tank exposed to atmosphere, and the closed type heat storage tank with structure separated from atmosphere. Although the size of the tank and its instal- lation place should be taken into account, the closed type tank is being usually employed by considering corrosion problems.
  • Page 72 8. SYSTEM DESIGN GUIDE HEAT SOURCE 4) Piping system The following items should be kept in your mind in planning / designing water circuits. a) All units should be constituted in a single circuit in principle. b) When plural numbers of the water heat source CITY MULTI unit are installed, the rated circulating water flow rate should be kept by making the piping resistance to each unit almost same value.
  • Page 73 8. SYSTEM DESIGN GUIDE HEAT SOURCE 5) Practical System Examples and Circulation Water Control Since the water heat source CITY MULTI is of water heat source system, versatile systems can be constituted by combining it with various heat sources. The practical system examples are given below. Either cooling or heating operation can be performed if the circulation water temperature of the water heat source CITY MULTI stays within a range of 10~45°C [50~113°F].
