QHS | Quantum HVAC Sensory System

Cut chiller energy without changing the chiller.

QHS is a sensing and control overlay for existing chiller plants. It retrofits to live equipment, integrates with the BMS, and gives operators a higher-resolution control layer for cooling performance.

Product definition

QHS is a retrofit control layer for chiller plants.

The platform installs around the plant the customer already operates. The chiller, BMS and site workflow stay familiar; QHS adds the sensing resolution and control logic needed to recover performance that conventional instrumentation cannot see.

Product components

01High-resolution sensor stack across chiller and auxiliary measurement points.
02C-Net distributed control logic for second-by-second setpoint refinement.
03BMS interface over standard protocols including BACnet/IP and Modbus TCP.

What QHS delivers

Six uplift modules, one installed platform.

01

Header and Q-TXV

Stabilises refrigerant superheat at the evaporator outlet and reduces losses from wet-suction or starved-evaporator operation.

02

Condenser water

Tracks approach temperature and tower performance in real time to reduce compressor lift.

03

Chilled water

Maintains delta-T across variable load and addresses low-delta-T operation.

04

VSD and tower fan

Coordinates variable-speed drives across the tower bank to capture fan energy savings.

05

MV entropic VSD

Extends control precision to medium-voltage compressor drives where the largest energy node sits.

06

Oil and refrigerant fingerprint

Continuously identifies mixture drift, degradation and contamination before it becomes a COP penalty.

Integration

Designed for retrofit, not replacement.

QHS mounts to existing pipework, transmitter housings and panel positions without breaking refrigerant containment or replacing OEM controls. It is designed to sit beside the building management system and improve the signal quality the plant acts on.

Operating envelope

Built for cooling assets that cannot pause.

A

District cooling

Portfolio-level percentage gains compound across large installed tonnage.

B

Commercial real estate

Chiller efficiency becomes a direct operating-cost lever across the estate.

C

Hospitality and healthcare

24-hour duty cycles require efficiency gains without comfort or reliability compromise.

D

Cold chain and industrial cooling

Energy performance translates directly into margin and process resilience.

Commercial case

The value is measured at the meter.

For a representative 500-ton chiller in UAE commercial operation, QHS is designed to recover roughly 380,000 kWh of annual electricity waste, equivalent to about AED 175,000 in operating-cost reduction at current tariff assumptions. Pilot sites are qualified by survey and verified against baseline operation.
