A Breakthrough in HVACR Monitoring and Control

Growing Customer Base Happy Customers Increased Revenue Reduced Callouts Reduced Time Wastage More profit per employee

Ensure Compliance Safe Workplace Drive Cost Down Increase Efficiency Increase Profit

• Real time information • Automation • Energy Efficiency • Measurable improvements • Gas monitoring and shutdown • Less Downtime

• Automatic alarm notification • Remote monitoring • Remote diagnosis and adjustment • Automated Reporting • Ability to prioritise

• Large Energy costs • Incentives to reduce energy usage • Change R22 and the old HFC’s to the

modern HFC’s and HC’s • Retrofit • New Equipment

• Gas Safety concerns

• Low Cost • 10.6” Touch Screen • 8 analogue inputs, 4 derived

inputs and 4 digital inputs • Can accept other sensors • 2 analogue and 8 relay outputs. • PID and On/Off Control • Alarms • PLC Logic • Auto and Manual Reporting • Trend displays • Remote Access • UPS

Uninterruptable Power Supply

• Simple Monitoring • Temperature, Pressure, Power, Water, CO2

• Gas Detection and Shutdown • Compressor Control. • Evaporator Control. • Superheat Control . • Defrost Control. • Oil Temperature Control

• Change to VFD • Compressor • Evaporator fans

• Change to Propane gas • Compressor staging • Adjust freezer temperature • Alarm on freezer doors opening times • Defrost Management • Cold Room setpoint

• Example 10kW • High Start up Current • VF Drive At 60% of full

speed requires approx 22% of full power

• Saving $9,000.00 p. a. Method % Running Power Energy CPH at 27c Cost per Year

On/Off 60 10kW 6kWh $1.62 $14,200.00

Variable Frequency 100 2.2kW 2.2kWh $0.594 $5,207.00

• Determine performance criteria eg • Water used, Energy used, CO2 produced • Running Costs

• Install suitable sensors and transmitters • Measure these parameters before making

improvements • Make improvements • Measure these parameters again • Reductions and savings

• Use P vs T table for the refrigerant gas • Enter 21 point curve into lineariser to convert

measured pressure into saturated temperature

• Use derived formula number 1 to calculate difference between actual temperature and saturated temperature.

• Set up PID controller on Derived input. • Output of controller feeds thermal expansion

valve • Set alarms on Superheat value to warn if

temperature difference gets too low.

Temp Difference

Pressure to temp

Actual temp

• Sensors: • Transmitters or trip modules

• Gas detection: • Infra red, Semiconductor, Heated wire bridge

• PLC sequence • feed valve , return valve, Shut down compresso, Start

exhaust fan • Siren Alert • Safety Lockout

Universal Easily affordable Solution. Energy savings quickly pay for the investment. Easy to install and operate. Strong relationships between contractor and

customer. Visibility for contractors and customer. Reduces time on site. Increases your profit. Grow your customer base.
