INTRODUCTION
Heat pumps are devices that move heat in a direction that is opposite of spontaneous flow. This means that a
heat pump moves heat from a location with a cooler temperature to another location with a warmer
temperature. The term heat pump can be used to describe a device that heats or cools a given location. Heat
pumps can be used in a variety of applications including refrigeration, air conditioning, and heating. The
function of heating or cooling is determined by the conditions of the environment and where the heat is
released by the heat pump. Heat pump technology has attracted increasing attention as one of the most
promising technologies to save energy. Areas of interest are heating of buildings, recovery of industrial
waste heat for steam production and water heating process.
OBJECTIVES
1. To observe Heat Pump cycle operating principal
2. To understand how reversing valve control the refrigerant
3. To determine the Heat Pump cycle

CONCLUSION
In conclusion, heat pumps offer efficiency, sustainability, and long-term cost savings over traditional
HVAC systems. Heat always travels from high temperature to lower temperature. Heat pump is a device that
pumps heat from a lower temperature to a higher temperature. This is opposite to the natural flow of heat,
but this applies for all refrigeration machines. However, the label ‘heat pump’ has evolved to define those
refrigeration machines which can be configured to provide both cooling and heating, commonly referred to
as “Reverse cycle”. Heat pump uses the same principle of vapor compression refrigerant cycle and has the
same basic components like a traditional air conditioner (compressor, condenser, evaporator, and expansion
device), except that it can reverse the refrigeration cycle or in other words, swap the functions of the two
heat exchanger (condenser and evaporator).
