Discrete Optimization in Architecture: Building Envelope

This publication explores the super modular structures that meet standards: they enable the construction of structurally sound free-form buildings, and they're made out of as few kinds of modules as attainable. Divided into components, it provides Pipe-Z (PZ) and Truss-Z (TZ) platforms. PZ is extra basic and kinds spatial mathematical knots through assembling one kind of unit (PZM).

Oil Heating Worksheet Introduction: When a customer complains about not enough heat from an oil-fired unit, the service technician should, as a first step, determine if the oil burner is delivering the amount of oil it was designed to deliver. Use the following procedures and the test instrument manufacturers’ instructions to determine the combustion efficiency of oil burning equipment. Tools Needed: tool kit, flue gas temperature thermometer, draft gauge, smoke tester, and carbon dioxide analyzer with the appropriate combustion efficiency chart or slide rule to use in combination with the various test results to determine the combustion efficiency.

Outdoor Unit The outdoor unit houses the compressor and outdoor coil, along with the other required components. The outdoor coil absorbs the heat from the ambient air so the refrigerant can take it indoors. The temperature of the outdoor ambient air determines both the suction and discharge refrigerant pressures. It is almost impossible to determine exactly what the proper pressures should be without the equipment manufacturer’s specifications. However, the higher the outdoor ambient temperature, the higher the refrigerant pressures.

Condensers are rated by the amount of total heat rejection (THR) they provide. In addition to the amount of heat removed from the cabinet or product, the heat of compression must also be removed from the refrigerant by the condenser. The compressor adds the heat of compression, which adds about 30% extra to the heat load absorbed by the evaporator. 30 = = = = condenser heat rejection specific heat of air constant dry bulb temperature air rise through the condenser approximate heat of compression To determine the cfm, use the following formula: cfm = Area × Velocity Water-cooled Condenser Water-cooled condensers usually require about 3 gallons per minute (gpm) per ton of refrigeration with a water temperature rise of 10°F db.
