Pregunta 2
Pregunta
What is the HVAC system that uses ventilation directly from the outside, passes the air over an evaporator, cooling it, and then discharges the air into the conditioned space?
Respuesta
-
Direct Expansion (DX)
-
Variable Air Volume
-
High-Velocity Dual-Duct System
-
Electric System
Pregunta 3
Pregunta
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.
Respuesta
-
Variable Air Volume (VAV)
-
Direct Expansion (DX)
-
Variable Refrigerant Flow System (VRF)
-
Induction System
Pregunta 4
Pregunta
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.
Respuesta
-
Variable Air Volume (VAV)
-
High-Velocity Dual-Duct System
-
Multizone System
-
Variable Refrigerant Flow System (VRF)
Pregunta 5
Pregunta
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?
Respuesta
-
Variable Refrigerant Flow System (VRF)
-
Direct Expansion (DX)
-
Induction System
-
Multizone System
Pregunta 6
Pregunta
Which type of HVAC system supplies air to a central mixing unit where heating and cooling coils produce separate hot/cold air-streams that are mixed by dampers controlled by thermostats and tempered, then delivered to a specific space?
Respuesta
-
Multizone System
-
High-Velocity Dual-Duct System
-
Variable Refrigerant Flow System
-
Constant Volume Single Duct
Pregunta 7
Pregunta
A Variable Refrigerant Flow system (VRF) is NOT appropriate for what types of spaces?
Respuesta
-
Large, open spaces (churches, theaters, auditoriums)
-
Small, confined spaces (apartments, single-family houses)
-
Wide, open spaces (open offices, retail stores)
-
Small, tall spaces (grain silos)
