Learning  objective: Identify and describe the  liquid  cooling  system  components  and  their operation. 1-1. 1-2. 1-3. 1-4. 1-5. 1-6. Three of the four methods of cooling  are  forced-air,  air-to-air, air-to-liquid.  What  is  the  fourth? 1.  Circulation 2.  Convention 3.  Conversion 4.  Convection When  utilizing  forced-air  cooling, an air filter must be provided at the air outlet to remove dust and dirt from the exhaust air. 1. True 2. False Heat is removed from the air passing by the heat producing source  in  an  air-to-air  cooling system by forcing it through what component? 1. Blower 2. RF  filter 3. Heat  exchanger 4. Fins Efficiency is increased in an air- to-liquid  cooling  system  by  the  use of  what  system  component? 1. Liquid  heat  exchangers 2. Dual  blower  motors 3. Larger  supply  lines 4. Duplex  strainers What  number  of  basic  cooling systems make up a typical liquid cooling  system? 1.  One 2. Two 3. Three 4. Four The  secondary  cooling  system transfers the heat load from the electronic  equipment  to  the  primary system. 1. True 2. False 1-7. 1-8. 1-9. 1-10. 1-11. 1-12. The Navy uses what number of basic configurations  of  liquid  cooling systems? 1. One 2.  Two 3. Three 4. Four Which  of  the  following  water resources  is/are  used  for  primary cooling? 1. 2. 3. 4. Seawater  only Chilled  water  only Seawater  and  chilled  water Potable  water  and  seawater The cooling water for the primary cooling  system  is  either  seawater or chilled water. The seawater is from the sea and the chilled water is from what source? 1. The  liquid  cooling  system 2. The ship’s air conditioning plant 3. The  ship’s  firemain  system 4. The  reefer  deck  supply  system When  temperature  range  is considered  to  be  critical,  what type of cooling system would most likely satisfy this need? 1. Type I 2. Type  II 3. Type III 4. Type IV What  type  of  liquid  cooling  system can  satisfactorily  be  operated  when seawater  temperatures  reach  95°F? 1. Type  I 2. Type II 3. Type III 4. Type IV In a primary cooling system, flow regulator may be known by what other term? 1. Expansion  tank 2. Demineralizer 3. Gate valve 4. Orifice plate 1
