General Information

General description

The heat pump of the split system air-air type allows air

conditioning both in summer as well as in winter by inverting

its operating cycle.

It is made up of two units: one to be installed outdoors and

another to be installed indoors.

To operate, they must be interconnected electrically and

frigoriﬁcally.

The combination of the BCHO heat pump as the outdoor

unit, with BCI, BLI or BVI as the indoor unit, allows easy

installation due to their limited dimensions and assembly

characteristics.

Nomenclature

equipped with internal protection of the motor. Includes an

electric heater for heating oil in the sump, which makes

start-ups easier and avoids oil being removing from the

compressor.

Coils

Of a large surface, made of grooved copper tubing and

notched aluminium ﬁns.

Fans BCHO

Centrifugal, with direct drive motor. Sufﬁcient pressure avail-

able for the installation of ducts and optional accessories.

Casing BCHO

Made of galvanised steel sheeting, ﬁnished with oven-poly-

merised powdered paint, which allows installing outdoors.

Insulated internally so as to avoid condensation of humid-

ity and reduce noise level. These units are equipped with

galvanised trays, with corresponding drains, for collecting

condensation from the coils.

Cooling circuit

Made of welded copper tubing. These units are supplied

with their corresponding optimised refrigerant charge and

having passed the maximum pressure and airtightness tests.

Refrigerant expansion is carried out by means of calibrated

holes and distributors located in both the indoor as well as

outdoor units. The circuit includes: four-way valve, suction

accumulator, high and low pressure switches, and suction

and discharge pressure intakes.

Refrigerant

These units are manufactured with R-407C refrigerant.

Fan (BVI, BCI or BLI indoor units)

Of the centrifugal type, 3 speeds, direct drive and mounted

on shock absorbers.

Complementary heater (indoor units)

Of the exposed wire type to allow fast heat dispersion, avoid-

ing temperature inertia that could affect the components.

Equipped with contactor and thermal protector.

Casing (indoor units)

Made of galvanized aluminium steel sheeting and ﬁnished

with oven polymerized powdered paint. Insulated internally

so as to avoid condensation of humidity and reduce noise

level.

Equipped with a galvanised tray, with corresponding drain,

for collecting condensation from the coil.

There is sufﬁcient space inside for ﬁtting the electric heat-

er.

On BLI units, the electric heater is installed externally, in

the duct.

Cooling interconnection

The cooling connection of the units should be made at the

time of installation at the job site. See the cooling connection

table in the Physical Data section.

Control Panel

Accessible directly from outside. Includes: connecting strip,

protectors, electronic board and probes, power supply con-

Technical Speciﬁcations

Compressor

Vertical Scroll type, mounted on antivibratory supports and

tactors, operating relay and transformer. Complies with the

European standards in force.

Thermostat

The BCHO units include, as standard equipment, the elec-

tronic DPC-1 thermostat.

For connecting the thermostat to the board, screened 10 x

0.22 mm² communication cable should be used.

Ambient thermostat DPC-1

Programmable digital thermostat with communication

This thermostat was designed to give close control of the

ambient temperature and graphic information regarding

the mode it is currently operating in. This control unit, in

accordance with the differential between the programmed

temperature and the ambient temperature, responds varying

the on/off cycles.

The liquid crystal display (LCD) normally indicates the ambi-

ent temperature, operating mode and whether the system is

in heat or cool.

It allows selecting different set point temperatures for cool and

heat, besides choosing between °C and °F on the display.

Fan operation can be in continuous or automatic mode, off

or in operation along with the compressor. Three speeds

can be selected.

The controls are beneath a cover.
