- 4. 4 How an Air Conditioner Works 1. Evaporator Cooling coils remove heat and humidity from the air using refrigerant. 2. Blower A blower (or fan) circulates air over the evaporation dispersing the chilled air. 3. Condenser Hot coils release collected heat into the outside air. 4. Compressor A pump that moves refrigerant between the evaporator and the condenser to chill the indoor air. 6. Filter Located in the air conditioning unit to remove particles from the air. 5. Fan A fan blows air over the condenser do dissipate the heat outside. 7. Thermostat A control system to regulate the amount of cool air that is distributed. CoolAutomation 2020

- 7. 7 The Importance of Feedback in HVAC Integration One-way communication is a basic “send & forget” control method: • Open control loop due to lack of feedback • No real-time monitoring • Unable to handle events & errors Two-way communication is fundamental for control systems: • Commands are acknowledged, retry upon failure • System status (on demand or periodic): state (on/off), temperature set point, mode (cool/heat/fan/auto), fan speed, swivel/louver, etc. • Events or errors notified - malfunctions, clean filter, room temperature, etc. “One-way” communication Two-way communication One-way wireless IR communication (No Feedback) Two-way wired communication (With Feedback) As a result - insufficient to implement an integrated and automated system The VRF and Split systems are open for two-way communication with automation systems Internet Apps Home Automation HA Scenarios HVAC System With Multiple Control Sources Central Controller Wired Control Panel IR CoolAutomation 2020
- 8. • The system is already “smart”, not designed to accept a non-native additional “brain” • Operation logic fundamental difference by design - no Modulation algorithm, just On/Off • Feature set is a subset of the system’s features and functions • One-way “mis”-communication – no feedback, hence, no real control loop • Wiring difference – 5 vs 2, forcing use of logic- conflicting solutions, hence, degradation (digital I/O vs communication protocols 8 The VRF Challenge for Smart Thermostats “So…, why don’t I use those nice looking and “smart thermostats” with these “smart” air- conditioning systems?!” CoolAutomation 2020

What system? • Multi-Split or VRF? • If the latter, Heat Pump or Heat Recovery? • Any BAS/BMS to integrate with? Equipment list! Who will use it? • Families, tenants, employees, guests • Segregated or shared • End user devices to use User profile & application! CoolAutomation 2020
- 12. Ambient Temperature can be measured from the Indoor unit or from the local wired thermostat controller. Often the owner prefers clean walls, no thermostats – for that, remote sensors will need to be used, their readings fed into the integrated system. It’s OK to remove the Wired Remote Control with its sensor, the indoor unit still has its own sensor, but the measurement will be imprecise (especially in heat mode). 12 Ambient Temperature Sensing Important for precise and fastest way to reach the desired comfort temperature.
