Textbook Question
Chapter 4, Problem 4.31P
Fora 3000-ft3 combination and exercise operation, it is desired to reduce the outdoor air intake rate to a minimum by filtering and air recirculation. (a) Design a system using filters having an efficiency of 0.50 and a pressure loss of 0.14 in. wg at 350 ft/min face velocity. Pressure loss should not exceed 0.20 in. wg. Outdoor air contaminants are negligible. (b) Discuss how the choice of a filter would be influenced in this case should the cooling load require a larger supply air rate than the ventilation.

(a) What is the total mass flow rate? (b) What is the dry bulb temperature? (c) what is the wet bulb temperature?
1. In less than 100 words, describe how the reciprocating air compressors (applicable to a particular purpose) may be used to save energy cost and still prevent disadvantages on other factors
2. Provide the evidence of investigation: Photographs, videos, calculations, information sources and other reasonable evidences (not downloaded from internet) during research work
3. Outcome: Cost implications or future projections / calculations from the idea(s
Calculate the EER rating of a 20 ton (240000 Btu) air conditioning unit with an
average electrical load of 30 kW.
An air conditioning plant supplies air to a room at a rate of 2.5 kg/s, the supply
air being made up of equal parts by weight of outdoor and recirculated air. The
mixed air passes through a cooler coil fitted with a by-pass duct, face and by pass
dampers being used for humidity control. The air then passes through an after
heater and supply fan. In a test on the plant, the following conditions (Table Qu
