Missouri 63166 Phone: (314) 694-1000 2-6 THERMINOL HEAT TRANSFER FLUIDS USED IN BUILDING SPACE HEATERS Commercial and large residential buildings have converted their heating systems to Therminol and significantly reduced their operating costs. In general, these systems provide total energy requirements except electricity. Monsanto's Akron office and laboratory complex is heated by Therminol. The system is described as: "a dual duct, variable volume heating and cooling system. Two main air conditioning systems are used: one for office space at 20% makeup air and the second for laboratories at 100% makeup air. Present building space air conditioned is 34,000 sq. ft. Total building is 42,000 sq. ft. Cooling capability is 323 tons, pro vided by an absorption machine using lithium bromide refrigerant to cool the chilled water loop. Condenser cooling water for the absorption machine is provided by an air coil cooling tower. Therminol 55 at 310"F provides direct heat to the concentrator of the absorption machine. Therminol 55 at 40CtF is heated by two 4.5 M BTU/HR liquid tube heaters with a lead-lag control function. The 400F Therminol 55 is circulated to a main header where secondary pumping pro vides constant temperature fluid from 160 to 375"F to the various users. Users include pre-heat and re-heat coils in the two main air handling systems; low pressure steam generator; domestic hot water; unit heaters; baseboard perimeter heaters, and the absorption machine. 0*,71064 NOTICE: "Nothing contained harain la to bo construed oi i recommendation to uao any product in conflict with any patant.

The entire system is automated and is unattended. The heating and cooling systems are over-sized to provide a 50% expansion of the building. Cost for the total air conditioning system was about $10.50/sq.ft, of building, which was very competitive with steam and hot water systems for that time and area." Cost savings with a Therminol system can be significant. In most areas, a licensed boiler operator is required to operate a pressure vessel such as the normal steam boiler. The Therminol system, being at atmospheric pressure, does not normally require an operating attendant. In fact, the normal Therminol heating system will run very well unattended. Overall thermal efficiency many times is also increased providing additional savings. Therminol 44, 55, 60 and 66 are natural fluids for heating applications.
