A manifold, found in many hydronic heating systems, is used only if... -
| | | | | | | | | | | | |
CORRECT ANSWER✔✔-the building has zoned heating
| | | | |
In an air cooling system, there are two coils through which refrigerant is
| | | | | | | | | | | | |
circulated. One, called a ___(1)___ , absorbs heat from the warm air
| | | | | | | | | | | |
passing over it. The heated refrigerant is then pumped through another
| | | | | | | | | | |
coil called a ___(2)___, where the refrigerant passes its collected heat to
| | | | | | | | | | |
|the atmosphere. - CORRECT ANSWER✔✔-1. evaporator
| | | | |
2. condenser
|
