Operating principle

The UR series brings together the ventilation, filtering and recovery sections into a single unit that also permits connection with various accessories for meeting the specific levels of comfort each environment requires.

Environmental comfort is provided by the extraction of stale air from the room and the simultaneous replacement of new air from the outside. The air is filtered adequately by means of filters on both supply and recovery. Energy recovery is provided by an efficient recovery unit with aluminium plates that makes it possible to save more than 50% of the energy in winter that would otherwise be lost through the expulsion of stale air.

The careful design of the product has made it possible to reduce the dimensions and thereby make it extremely easy to install in suspended ceilings or in cramped areas, improving, among other things, the accessibility for the maintenance of all the machine components, as well.

The range consisting of seven models (with rated air flow rates of 350 m³/h to 3300 m³/h), available in both vertical and horizontal versions

The structure consists of self-bearing sandwich panels 20 mm thick made of galvanised steel plate with insulation formed by injected polyurethane (density 40 kg/m3). The steel sheet is fitted with pre-shearing near the opening for the aeraulic connections (in such a way as to permit the motorfan assemblies to be oriented in different ways), and near the exits of the manifolds of any water-heating coil (URxxA version) for plumbing connections.

Inspection capacity

It is possible from below (ceiling installation) by easily dismantling the panels.

Supply and intake motor- fan assembly

The forward-curved centrifugal fans are double inlet directly coupled to electric motors. Electric motors are single speed UR for sizes 100, 150, 210, 330 while four-speed for sizes 35, 55 and 75. The fans are aspiring for the recovery to ensure maximum uni- formity of flow on the recovery itself, and hence the maximum yield.

Filters

Free-cooling operation

ESTERNO OUTDOOR

INTERNO INDOOR

C B

A Free-cooling function requires the expelled-air flow from the room does not affect the heat recovery unit going directly to the outside through a channel attached to the vent (A).

The fresh air flow thus passes through the filter and the heat recovery unit without being touched by the heat

exchangers.

To use the free-cooling function it is therefore necessary to have a channel to couple to the opening (A) and then position two gates with opposite action (B and C).

When the external air temperature is near the ideal temperature for the

room, the gate (C) is closed while gate (B) is open.

Fan characteristic curves

The characteristic curves of the fans are shown in the following diagrams, for each base unit size in the horizontal and vertical configurations.

The curves refer to the maximum and minimum fan speed. For intermediate speeds the curves move in the range between the two curves shown.

The static pressure available is read on

the ordinate, for a determined air flow expressed in m³/h providing that a supply channel equal to at least one meter is installed downline from the fan.

The pressure drops for each accessory to be subtracted from the value of the useful static pressure read in function of the flow rate are shown in the table next to each graph.

The static pressures are net of the pressure drops of the heat recovery unit and the clean filters.

Heat recovery unit performance curves

The following diagrams represent the heat recovery units’ performance (efficiency, recovered power) in function of the air flow for each unit size.

The performance refers to the following conditions:

• Winter functioning: fresh air flow rate equal to the expulsion air flow rate; external air temperature on input - 5° C, 80%

RH; room air temperature 20° C, 50% RH.

• Summer operation: fresh air flow rate equal to the expulsion air flow rate; external air temperature 34° C, 50% RH; room air temperature 26° C, 50% RH.

For conditions other than the ones shown above, the values read in the diagram must be multiplied by the respective corrective coefficient in the following tables.

WATER TYPE HEATING COIL YIELD CURVES

INDOOR HEATING COIL

The heat power exchanged by the heating coils downline from the heat recovery units can be read for each unit size and in function of the air flow in the following diagrams.

The diagrams refer to:

• air temperature on input to the coil (that coincides with the air temperature leaving the heat recovery unit) equal to 8°C;

• water temperature entering/leaving the coil equal to 45/40°C, 70/60°C and 80/70°C respectively.

For input air conditions of coils other than those shown above (6°C, 10°C, 12°C), the value read on the ordinate in the diagram must be multiplied by the corrective coefficient (K) shown in the tables below.

The pressure drops on the water side of the heating coil situated immediately after the heat recovery unit and the reheating coil in the “coil module” are shown in the following diagrams.

The pressure drops on the air side can be read in function of the air flow rate and the size, on the ordinate axis.

As far as the pressure loss on the water side is concerned the following proce-

dure must be adopted:

• in diagram 1, when the thermal power required by the coil and the thermal head of the water is known, the water supply flow rate is found on the ordinate axis;

• in diagram 2, when the water flow rate taken from diagram 1 is known, the pressure drops of the coil (including the manifold

pressure drops) are read on the ordinate axis. The curves proposed in diagram 2 refer to the 80/70°C supply water: to get the water side pressure drops for other supply temperatures, the values read on the ordinate in diagram 2 must be multiplied the coefficients present in the table.

Cooling coil capacity tables

COOLING WATER COIL (BF, MPW, MPX)

It is possible to read the operating data for the water cooling coil in the “coil module” in the following table for each unit size and dependent on the air flow rate.

LEGEND

Pa: Air flow rate [m³/h]

Tia: Input air temperature [°C]

UR: Relative humidity [%]

Tua: Air output temperature [°C]

Qtot: Total refrigerating capacity [kW]

Qsen: Sensitive refrigerating capacity [kW]

Pw: Feed water flow rate [l/h]

DPw: Water side pressure drops (including the coil manifold pressure drops) [kPa]

DPa: Air side pressure drop [Pa]

It is possible to read the operating data for the direct expansion cooling coil in the “coil module” in the following table for each unit size and dependent on the air flow rate.

The performance refers to the following conditions:

• R407C refrigerant; average evaporation temperature 5°C; condensing temperature 47°C.

• R410A refrigerant; average evaporation temperature 9°C; condensing temperature 47°C.

LEGEND

Pa: Air flow rate [m³/h]

Tia: Input air temperature [°C]

UR: Relative humidity [%]

Tua: Air output temperature [°C]

Qtot: Total refrigerating capacity [kW]

Qsen: Sensitive refrigerating capacity [kW]

DPf: Frigorigenic fluid side pressure drop DPa: Air side pressure drop
