What does the evaporator do in a refrigeration system? The evaporator works the opposite of the condenser, here refrigerant liquid is converted to gas, absorbing heat from the air in the compartment. When the liquid refrigerant reaches the evaporator its pressure has been reduced, dissipating its heat content and making it much cooler than the […]

How do you vent a condensing furnace?
How do you vent a condensing furnace? Venting. A condensing furnace doesn’t require a chimney. Instead, these furnaces are vented in one of two ways: Direct vent (two-pipe) vent system – This system uses one pipe to bring in outside air for combustion and another to remove exhaust gases. How are high efficiency furnaces vented? […]

Which statement explains why metals are good conductors of electricity?
Which statement explains why metals are good conductors of electricity? Metals are an excellent conductor of electricity and heat because the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting […]
