INTRODUCTION COMFORT AIR CURTAIN

1. . Introduction

1.1 About this manual

1.1.1 General

This manual describes the installation, operation and maintenance of the comf

ort air curtain model CA

with CHIPS control. The manual also provides instructions and information on service operations.

1.2 About the automatic CHIPS control

The CHIPS control matches the strength and heat of the air curtain to changing weather conditions. This reduces energy consumption and improves comfort through selection of the optimum setting under all circumstances. CHIPS stands for “Corrective Heat and Impulse Prediction System”.

The operation of the air curtain is based on the outside tem

perature and the room temperature near the air curtain.

1.3 How to use this manual

If you are unfamiliar with the comfort air curtain, read this manual section by section.

If you are familiar with the device, you may use this manual as a r

eference. Refer to the table of contents for looking up

information.

1.4 About the unit

1.4.1 Applications

The comfort air curtain is inten

ded for the separation of climates between two rooms, and for the heating and filtering (filter class EN779-G2) of air. The unit is installed above the doorway, across its full width.

The free-hanging model is designed for free, visible installation above the door.

The recessed model is designed for integration into a false ceiling or into a cove, with the inlet opening possibly at some distance from the unit.

The cassette model is designed for installation above a false ceiling, with the inlet opening close to the unit and with easy access to the unit.

CA2 V and CA2 Q

The CA

V/CA2 Q air curtain is connected to a Daikin direct expansion system. The air blown through the unit is heated by the cooling medium. The air curtain is controlled and operated partly by the Daikin system and partly by the Biddle system.

MANUAL INTRODUCTION

Version: 6.1 (05-12-2011) 7

The system has a number of limitations:

• The unit is only suitable for use in Daikin direct expansion systems.

• The unit is not suitable for cooling.

• The temperature control is less accurate than with water or electric heating.

• The Daikin system has to be active at all times.

Other versions and intended use.

On request, versions can be supplied for other applications.

Warning:

w Applications other than those described above are

not considered to be an intended use. Biddle

assumes no responsibility for damage or injury

resulting from applications other than the intended

use. The intended use also implies observance of

and compliance with the instructions in this

manual.

1.4.2 Function

The air curtain blows out a stream of heated air straight down, thus achieving the following:

• The exchange of air between two rooms due to temperature differences (convection) is stopped.

• The cold air entering across the floor due to draught is heated.

Depending on the air curtains setting, the unit can also blow unheated air.

1.4.3 Models and type designations

Ta b l e 1-2 provides an overview of available models of the comfort air curtain and the corresponding type designations. Combined, the type designations constitute the type code, for instance: CA2

S-100-W-F. Not every combination is available.

The air curtain operates as standard with fully automatic control. Depending on the selected settings, the air curtain can also be controlled manually.

In automatic mode, the unit operates under CHIPS control. This con

trol matches the strength and heat of the air curtain to changing weather conditions. This reduces energy consumption and improves comfort through selection of the optimum setting under all circumstances. CHIPS stands for “Corrective Heat and Impulse Prediction System”.

The operation of the air curtain is based on the outside temp

erature and the room temperature near the air curtain.

Adjust the automatic strength control

In automatic mode, the strength and temperature of the air stream are controlled automatically. Due to weather conditions, you might want to adjust the automatic setting. If you feel a cold draught along the floor, you can increase the automatic strength.

Note:

n The adjustment of the automatic strength is not always

directly translated into a different fan speed.

Manual setting of the strength

With the manual setting, you have 6 strengths to chose from. To achieve maximum climate separation with minimum energy consumption, Biddle recommends to select the lowest strength at which no draught occurs. This setting may need to be changed during the day.

3.4.3 Recommended setting of the air curtain

To obtain the maximum separation effect and the greatest comf

ort possible with the least possible energy consumption,

Biddle recommends use of the fully automatic CHIPS control.
