Evaporator units play a critical role in modern HVAC systems by absorbing heat from the environment and enabling efficient cooling performance. Choosing the right type of evaporator is essential for optimal energy efficiency, reliability, and comfort. In this article, we’ll explore the main types of evaporator units used in HVAC applications, with a particular focus on high-performance solutions from Clivet, one of Europe’s leading HVAC brands.
DX (Direct Expansion) Evaporator Units
What They Are:
Direct expansion evaporator units use refrigerant that evaporates directly within the coil to absorb heat from the surrounding air.
Applications:
-
Residential and small commercial buildings
-
Split and multi-split systems
-
VRF/VRV systems
Clivet Solutions:
Clivet offers several compact and energy-efficient DX units tailored for both residential and light commercial use. Their systems include inverter-driven compressors for superior control and reduced energy consumption.
Chilled Water Evaporator Units
What They Are:
These units operate with chilled water supplied by a central chiller. The water circulates through the coil, cooling the air as it passes over.
Applications:
-
Medium to large commercial spaces
-
Hospitals, shopping centers, airports
-
Centralized HVAC systems
Clivet Advantage:
Clivet’s chilled water fan coil units and air handling units (AHUs) are engineered for precision and durability. Their AHUs feature modular designs, high-efficiency fans, and customizable options for complex projects.
Ceiling Cassette Evaporator Units
What They Are:
Ceiling cassette units are a type of DX unit designed to be mounted flush with a ceiling, distributing air in four directions.
Applications:
-
Open-plan offices
-
Retail stores
-
Areas where wall space is limited
Clivet Features:
Clivet’s cassette systems, such as those in the ELFO range, are known for their quiet operation, sleek design, and integrated air purification technologies. Some models include motion sensors and adaptive air distribution.
Wall-Mounted and Console Evaporators
What They Are:
These units are typically installed on or near a wall or floor and are often seen in ductless split systems.
Applications:
-
Residential buildings
-
Hotels and guest rooms
-
Small commercial spaces
Clivet Solutions:
Clivet provides stylish wall-mounted and floor console units that combine aesthetic appeal with energy-efficient performance. The ELFOFresh series adds fresh air management for improved indoor air quality.
Ducted Evaporator Units
What They Are:
Ducted systems hide the evaporator within a ceiling or wall space, distributing air through ducts to multiple zones.
Applications:
-
Luxury residences
-
Commercial offices
-
Hospitals and educational institutions
Why Clivet:
Clivet ducted units are ideal for projects requiring a clean interior look with flexible zoning. Their Smart Management Systems ensure stable climate control and remote monitoring.
Custom Air Handling Units (AHUs)
What They Are:
Custom AHUs include evaporator sections tailored to specific HVAC needs, such as humidity control, filtration, and energy recovery.
Applications:
-
Industrial facilities
-
Cleanrooms and laboratories
-
Public institutions
Clivet’s Engineering Strength:
Clivet’s modular AHUs are designed for highly demanding applications, supporting features such as HEPA filters, energy recovery wheels, and integrated BMS (Building Management System) compatibility.
