Solicitatio n Section

Vendor Question State’s Response two SMC2 condensers, and two 10-cubic-inch compressors. 28' LTV:

TA73HP rear evaporator plus FM55 flush-mounted evaporator, SMC3L plus SMC2 condensers, and one 15-cubic-inch plus one 13-cubic-inch compressor.

3.9.6 and 3.9.12 through 3.9.15

Continued:

The complete-system capacities include the contribution of the OEM driver’s dash air-conditioning system identified as Evaporator #1 in Section 3.9.10. The auxiliary passenger systems are separately controlled and sized based upon the actual interior dimensions, floor plans, passenger layouts, and expected thermal loads of the vehicles offered. The proposed 28-foot configuration provides combined evaporator airflow of approximately 2,422 CFM and therefore meets the Section 3.9.15 airflow requirement.

The TA77 proposed for the 23'/25' layouts is rated at 2,220 CFM at zero static rather than the nominal 2,400 CFM stated for the basis-of-design evaporator. The proposed condenser arrangements also differ from the single three-fan condenser configuration described in Section

3.9.13. The 23'/25' configuration

uses two SMC2 condensers, providing four condenser fans and greater combined heat-rejection capacity than the named basis-of-design condenser. The 28' configuration uses one SMC3L three-fan condenser together with one SMC2 two-fan condenser to support the dual-compressor system and the higher sensible and latent cooling load. Trans/Air’s proposed systems use matched evaporator, compressor, and condenser configurations selected to meet or exceed the vehicle-level cooling performance required by Section

3.9.6 at 95°F ambient temperature and 80% relative humidity. Complete HVAC performance under these conditions depends upon evaporator effectiveness, refrigerant mass flow, compressor capacity, condenser heat-rejection capacity, sensible and latent heat removal, and passenger-
