COURSE PROJECT 3
DESIGN AND ANALYSIS OF A HEAT PUMP SYSTEM FOR HEATING AND COOLING
Assignment Date: 21 November 2021
Due Date: 4 December 2021
Project Description
As a mechanical engineer, you have been assigned the task to design and analyse a heat pump system,
using refrigerant R134a as a working fluid, for a house located in Toronto. The isentropic efficiency for
compressor in the cycle ranges between 70% and 85%. The heating load ranges between 10 kW and
20 kW, and the cooling load ranges between 8 kW and 16 kW. Note that each one of you is requested
to select different cooling and heating loads and isentropic efficiency value for the calculations.
Table-1: Cycle temperatures.
Parameter Value
Evaporating temperature 1 oC
Superheat 8 oC
Condensing temperature 80 oC
Subcooling 5 oC
Based on the data provided in Table-1, you are requested to fulfill the following tasks:
1) Draw the schematic for a single-stage heat pump cycle
2) Write the thermodynamic balance equations for all system components
3) Analyse the heat pump cycle in CoolPack software. You can use the default input data in the
software and configure the system based on the selected heating and cooling loads. Select a suitable
isentropic efficiency within the indicated range.
4) Determine the mass flow rate of refrigerant R134a required to meet the chosen heating and cooling
loads from the software.
5) Find the compressor power input requirement and the COP of the cycle in both the heating and
cooling modes
6) List all the thermodynamic properties in a table at each state point in the cycle
7) Demonstrate the heating and cooling cycles on a T-s diagram.
8) Change the refrigerant from R134a to R12 and study the effect on the compressor power input
equirement, refrigerant mass flow rate requirement and COP’s of both the heating and cooling
modes
9) Prepare a report describing the problem statement, analysis, results and discussion, closing remarks
and references. Include a cover page with project title, student information and signature.
Note: Along with calculations and required tables and graphs, you are also requested to include the
esults of the screenshots obtained from the software in your report.
Remarks:
• CoolPack software can be downloaded from: https:
www.ipu.dk/products/coolpack/
• The final report will be submitted through Turnitin via Canvas
• Every student is expected to choose a different heating and cooling load as well as
different isentropic efficiency.
