illustrates the vapor-compression process of
transferring heat from a cold area to a warmer one
using
a
refrigerant,
involving
four
main
components: a COMPRESSOR, a CONDENSER,
an EXPANSION VALVE, and an EVAPORATOR.
(a)
is a Special type of Fluid / Gas
used in refrigeration air Conditioning and heat

REFRIGERANT
CONDENSER
EVAPORATOR
is the part of the refrigeration
system
which
increases
the
pressure,
and
corresponding temperature of the refrigerant so it can
release heat. The Heart of Refrigeration System
COMPRESSOR
CONDENSER
EXPANSION VALVE
is
the
component
of
the
refrigeration system which releases heat to the
environment.
CONDENSER
EXPANSION VALVE
is the component of the
refrigeration system which expands (lowers the
pressure and temperature) of the refrigerant. This is
also Called as a Metering Device
COMPRESSOR
EXPANSION VALVE

Electronic Extension Valve (EXV)
The process begins with the
thermostat sensing bulb placed in the environment or
appliance being controlled.
Pressure Transmission
Temperature Sensing
Mechanical Activation
The bulb is filled with
a temperature sensitive liquid. When the temperature of
the surrounding medium rises, the fluid inside the bulb
expands.
Fluid Expansion/Contraction
Pressure Transmission
This expansion or
contraction of the fluid creates a corresponding change.
This pressure is transmitted through the slender
capillary tube.
Pressure Transmission
Temperature Sensing
The other end of the
capillary tube is connected to a bellows or diaphragm.
The pressure from the expanding fluid pushes against
the bellows, causing it to expand and the diaphragm to
move.
Mechanical Activation
Switch Operation
is a device that uses continuous electrical
or pneumatic signals to regulate HVAC equipment.
Instead of processing data digitally, it responds
directly to changes in voltage, current, pressure, or
resistance from sensors
ANALOG TYPE CONTROLLER
DIGITAL CONTROLLER
The movement of the bellows or
diaphragm then triggers a snap-action switch. This
action opens or closes electrical contacts
Switch Operation
Temperature Sensing
By opening or closing these
contacts, the thermostat turns the connected heating or
cooling system on or off, thereby regulating the
temperature to the desired set point.
Temperature Regulation
Temperature Regulator
Is a microprocessorbased device used to monitor, regulate, and optimize the
performance of HVAC systems. It processes input
signals from sensors, compares them with programmed
setpoints, and generates output signals to control
devices like fans, compressors, dampers, and valves
