1. Introduction

k.Air is a pre-programmed controller for air conditioning and ventilation units.

k.Air ensures simple commissioning, application flexibility, advanced connectivity and usability, thanks to

the following features:

l preloaded configurations of air handling units, configuration tool or manual procedure;

l modular concept for the management of additional configurations by coupling together c.pCOe

expansion modules via a built-in serial card;

l management of high-efficiency direct expansion units

l application of energy saving and adiabatic humidification management algorithms;

l advanced connectivity, thanks to three serial ports and an Ethernet port, certified Bacnet protocol and

remote control via tERA.

l integrated web server interface.

k.Air is available in two sizes: mini P/N P+DA00FHD*FK and large P/N P+5A00SFC*LK. Both models share

the same software functions, however they differ in terms of the number and characteristics of the

available inputs/outputs and serial communication ports.

The number of inputs/outputs can be expanded using up to 4 c.pCOe expansion modules.

Fig.1.a

It is possible to connect CAREL temperature and humidity probes, active differential pressure probes,

flow switches and thermostats, with control functions or to signal alarms in the event of a fault.

The application offers numerous pre- set basic unit configurations (I/O map and related associated

functions); if the unit being configured deviates from these models (e.g. if the devices are connected to a

different input/output or the unit has other devices and functions), the software can be reconfigured on

the PGDE display or using the configuration tool.

HumiSonic ultrasonic humidifier

Adiabatic ultrasonic humidifier for installation inside the air handling unit.

Installed directly in the air flow, humiSonic atomises water into very small droplets (5 µm on average),

which are instantly absorbed by the air flow. This is proposed as a high energy efficiency alternative to

steam humidification.

It is available in the Ventilation and Compact versions.

In the Ventilation version, it has capacity of 2 kg/h at 18 kg/h, and is designed for installation inside air

handling units or ducts.

It comprises an atomising production and distribution unit and an external electrical panel. For more

details see manual +0300063EN.

Fig.1.m

In the Compact version, it has a capacity of 0.5 kg/h to 1 kg/h, and is designed to be built into compact

units, such as heat recovery units, fan heaters, fan coils, etc. See manual +0300056EN.

Humifog high pressure sprayer

High pressure adiabatic humidifier for humidity control and evaporative cooling. humiFog combines an

intelligent pumping station with a modular distribution system, equipped with special nozzles capable

of maximising water atomisation and allowing a short absorption distance. Inverter modulation ensures

very accurate control of pump speed, reducing energy consumption and optimising water use. With

capacities from 100 to 1000 kg/h, it is designed for applications with high humidification demand, where

precision and hygiene are distinctive factors.

uChiller

μChiller is Carel’s solution for the complete management of direct expansion units. The maximum

configuration manages 2 compressors per circuit (On/Off or BLDC), up to a maximum of 2 circuits (using

an expansion card for circuit 2). The distinctive element of μChiller is complete control of high-efficiency

units through integrated management electronic expansion valves (ExV) and the brushless DC

compressors, guaranteeing

greater compressor protection and reliability and high unit efficiency. CAREL’s “APPLICA” app, available

on Google Play for the Android operating system, makes it easier to configure parameters and

commission the unit. Operation of μChiller is described in the user manual +0300053EN
