Try these first

1. 1.

   What is the primary function of an evaporator in VARS?

   Hint

   Think about the cooling function of the system.

2. 2.

   Can you name a common refrigerant used in VARS?

   Hint

   What was mentioned as a gas that absorbs heat?

3. 3.

   What is the role of the evaporator in VARS?

   • To condense refrigerant
   • To absorb heat
   • To pump the solution

   Hint

   Remember its function related to cooling.

4. 4.

   True or False: The refrigerant in VARS can sometimes be harmful.

   • True
   • False

   Hint

   Recall the properties of the refrigerants used.

5. 5.

   Given that an evaporator utilizes ammonia at low pressure, calculate the cooling capacity if it absorbs 5 kWh of heat energy?

   Hint

   Remember the relationship between energy absorbed and cooling capacity!

6. 6.

   Discuss the implications of refrigerant carryover in the context of an evaporator's performance and suggest potential solutions.

   Hint
