MiravoIndustrial Chiller
Air-cooled process chiller with dual-stage compressor, refrigerant circuit monitoring, and coolant loop. 10-ton class with R-134a.
What it is
An air-cooled process chiller with dual-stage compressor operation, R-134a refrigerant circuit monitoring, and a coolant loop that couples to downstream assets. Grounded in 10-ton SMC and Carrier process chiller specifications, R-134a thermodynamics, and ASHRAE 90.1 efficiency standards.
Used in
smart-factory— machining-area coolant loop, serving CNC spindlescommercial-building— central chilled-water plantbackup-power— data center hall cooling
What it tracks
| Member | Why it matters |
|---|---|
return_temp | Coolant returning from the load — drives compressor demand. |
supply_temp | Conditioned coolant out to the load. |
delta_t | Load indicator. |
compressor_stage | Staged capacity control (0 / 1 / 2). |
compressor_active | Run state. |
refrigerant_pressure_suction | Low-side pressure, charge indicator. |
refrigerant_pressure_discharge | High-side pressure, condenser-loading indicator. |
power_draw | Electrical consumption, load-correlated. |
coolant_flow_rate | Loop-side flow. |
compressor_run_hours / compressor_starts | Duty counters for wear and cycling. |
Fault modes
refrigerant_leak— suction-pressure decay, supply-temperature climb, capacity loss.compressor_failure— total cooling loss, downstream thermal runaway.dirty_condenser— discharge-pressure rise, efficiency drop, compressor duty climb.
Key parameters
| Parameter | Default | Unit |
|---|---|---|
cooling_capacity_kw | 35 | kW |
supply_temp_setpoint_c | 12 | °C |
Use cases
