Frage 3
Frage
What type of all-air HVAC system forces air from a central plant at a constant temperature through a single duct into a conditioned space? A thermostat controls the volume of the air to respond to the client's needs.
Frage 4
Frage
Which type of HVAC system consists of two-ducts running parallel to each other, one carrying hot-air, the other, cold. The two streams meet in an mixing box, controlled by a thermostat, that mixes the air to the desired conditions.
Antworten
-
Variable Air Volume (VAV)
-
High-Velocity Dual-Duct System
-
Multizone System
-
Variable Refrigerant Flow System (VRF)
Frage 5
Frage
Which type of HVAC system consists of a single compressor/condenser that connects to multiple evaporators located in different zones (rooms), and which uses refrigerant rather than water to transfer heat or absorb heat from a space?
Frage 6
Frage

Multizone System
-
High-Velocity Dual-Duct System
-
Variable Refrigerant Flow System
-
