1A wall has area 50 m², U-value 0.60 W/(m²·K) and a specified steady temperature difference of 12 K. Ignoring solar and storage effects, what conduction gain is calculated?

A.0.36 kW

B.3.60 kW

C.0.030 kW

D.0.72 kW

Explanation: The steady gain is UAΔT = 0.60 × 50 × 12 = 360 W = 0.36 kW. Actual cooling-load methods may also account for solar exposure and delayed heat release.

2A simplified glazing calculation uses area 12 m², incident solar irradiance 500 W/m² and effective solar heat-gain coefficient 0.35 including the specified shading condition. What instantaneous solar gain results?

A.6.0 kW

B.2.1 kW

C.1.05 kW

D.17.1 kW

Explanation: The gain is 12 × 500 × 0.35 = 2100 W = 2.1 kW. The supplied effective coefficient already includes the stated shading condition, so that condition must not be applied a second time.

3For the specified activity, each of 20 occupants contributes 75 W sensible and 55 W latent heat. What total occupant heat gain is used?

A.1.50 kW

B.1.10 kW

C.2.60 kW

D.3.00 kW

Explanation: Each person contributes 75+55 = 130 W total. Twenty people therefore add 2600 W, comprising 1.50 kW sensible and 1.10 kW latent gain.

4A room has sensible cooling load 18 kW. Supply air enters at 14°C and room air is 26°C. Using dry-air specific heat 1.02 kJ/(kg·K), neglecting other sensible effects, what dry-air mass flow is required?

A.0.735 kg/s

B.1.80 kg/s

C.2.94 kg/s

D.1.47 kg/s

Explanation: Mass flow is 18/[1.02 × (26-14)] = 1.47 kg/s. This is a sensible balance; latent load and outdoor-air requirements need separate checks.

5A moisture source adds 2.4 kg/h of water vapor to a room. Using latent heat 2500 kJ/kg, what latent load does this represent?

A.1.67 kW

B.6.00 kW

C.0.667 kW

D.16.7 kW

Explanation: Latent heat rate is 2.4 × 2500/3600 = 1.67 kW. Hourly moisture flow must be converted to kilograms per second before multiplying by kJ/kg.

6Outdoor ventilation air enters at enthalpy 78 kJ/kg dry air and is compared with room air at 50 kJ/kg dry air. For 0.50 kg dry air/s, what total outdoor-air cooling contribution is calculated?

A.39 kW

B.14 kW

C.25 kW

D.28 kW

Explanation: The contribution is dry-air mass flow times enthalpy difference: 0.50 × (78-50) = 14 kW. Using enthalpy includes both sensible and latent contributions under the specified conditions.

7A room receives a short burst of radiant solar gain. Why may its cooling-load peak occur later than the gain peak?

A.Radiant energy heats room air instantly, and all delay is necessarily caused by the thermostat

B.The design method always averages solar gain uniformly across 24 hours

C.Room surfaces absorb energy and release part of it later to the air

D.The glazing's U-value alone determines the time delay, regardless of room construction

Explanation: Radiant gains first heat surfaces and furnishings rather than immediately heating all room air. Thermal storage and later convection can shift and reduce the instantaneous cooling-load peak relative to the heat-gain peak.

8A common air handler serves east and west zones. At 09:00 their loads are 18 and 8 kW, with 6 kW internal and 4 kW outdoor-air load. At 15:00 they are 10 and 22 kW, with 8 and 5 kW respectively. At 18:00 they are 6 and 16 kW, with 4 and 3 kW respectively. For these three design cases, what coincident peak applies?

A.53 kW at 15:00

B.40 kW at 09:00

C.29 kW at 18:00

D.45 kW at 15:00

Explanation: The case totals are 36, 45 and 29 kW, so 15:00 controls at 45 kW. Summing each component's separate maximum would incorrectly produce 53 kW from loads that do not all coincide.

9Lighting adds 4 kW of heat gain: 40% immediately convective and 60% radiant. In this exercise, the hourly response method credits the full convective gain and 50% of the radiant gain to this hour's cooling load, with no earlier radiant gains. What lighting cooling load results?

A.2.8 kW

B.4.0 kW

C.2.0 kW

D.1.2 kW

Explanation: The immediate convective contribution is 4 × 0.40 = 1.6 kW. The radiant contribution for this hour is 4 × 0.60 × 0.50 = 1.2 kW, giving a total of 2.8 kW under the supplied response assumptions.

10A room needs 24 kW sensible and 6 kW latent removal. Supply air is 12 K below room temperature and its humidity ratio is 0.002 kg/kg dry air lower. Use cp = 1.02 kJ/(kg·K) and hfg = 2500 kJ/kg. What minimum dry-air flow has sufficient capacity for both balances at these stated differences?

A.1.20 kg/s

B.1.96 kg/s

C.3.16 kg/s

D.0.76 kg/s

Explanation: The sensible requirement is 24/(1.02 × 12) = 1.96 kg/s and the latent requirement is 6/(2500 × 0.002) = 1.20 kg/s. The larger value controls this capacity check; actual controls and resulting room humidity still require design review.
