What component starts the indoor fan motor in residential air conditioners?
A. Fan Relay
B. Thermistor
C. Bimetallic Element
D. Motor Starter
Homework Answers
In AC indoor indoor fan motor starts when fan relay which is connected to thermostat allows user to switch fan ON. This relay will put indoor fan in FAN ON mode and it will run even the system switch is in OFF state. When relay is in AUTO position then it will start cooling.

Consider a typical residential heat pump system operating between an indoor temperature of 70F and an outdoor temperature of 45F. The Carnot COP of heating for this system is over 30 (you can determine this exactly). Yet, the actual COP of heating for actual systems today runs around 4-5. Ok, where did the COP go? That is, in thermodynamic terms- what are the irreversibilities, what components or processes are guilty? Don't forget the whole system should include some power hungry...

Externalities I Perhaps ironically, air conditioners produce heat as a waste product (to say nothing of any externalities from energy consumption). Air conditioner’s waste warm up nearby outdoor areas. This effect can be substantial in dense cities. Suppose that the following are the benefits/ costs from running an air conditioner on a 90 degree day (Q is the temperature reduction enjoyed by the consumer of the air conditioning): MPB=MSB=30-Q MPC=10 External Cost=5 a) Graph the private/social marginal benefit/cost curves described...

Problem 2: A residential air-conditioner with an actual cooling capacity of 14.06 kJ/s (4 tons), cools and dehumidifies a steady stream of air flowing over the cooling coil. Actual states for the Refrigerant 134a are given Notice that the compressor efficiency is less than 100% and there are small pressure drops given for the heat exchangers. The coefficient of performance is 3.51 for the actual cycle. Changes in kinetic and potential energy are negligible. The warm indoor air temperature entering...
