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 fans to move air across the heat exchangers.

Plus, how high value can we really get?

a)Problem Statement

b) Idealizations and Assumptions

c) Analytical Development

d)Discussion of Results

    A heat pump operating with R-134a is used to maintain an indoor temperature of 21°C using heat from the bottom of a lake that stays at 2°C. Assume an 80% efficient compressor. If the heat pump supplies 100 kW of energy to the building, calculate the required mass flow rate and COP for the heat pump. Calculate a few data points to plot the effect of a 10°C temperature range at the cold side on required mass flow rate and...

    During winter time a heat pump is operating on a heating mode to maintain a living room at 23oC during which the outside temperature is -5oC. The system is using R134a as a working fluid. The refrigerant leaves the condenser at 28oC and enters a compressor at -10oC. The refrigerant flow rate is 0.12kg/s. Assume an ideal VCC to evaluate the system and report the followings: a. Process diagram b. Heating capacity kJ/hr c. Coefficient of performance of the system...
