5. HRVBBLHA HRVBBSVA HEAT RECOVERY VENTILATORS Product Data The Heat Recovery Ventilation HRV system offered by Bryant is the finest on the market today The HRV provides efficient and cost effective heat recovery during the heating season when needed most As temperatures drop below 23 F 5 C indoor air is recirculated periodically through the heat exchanger core to prevent frost from forming Competitors methods of supplementary electric defrost waste energy Unlike rotary wheel heat exchangers which mix air streams these cross flow or counterflow heat exchangers ensure that there is no mixing of the stale air stream with the fresh outdoor air stream A filter installed on the incoming outdoor air stream removes large airborne particles from the intake air stream before they enter the heat exchanger and reduces the maintenance required The units acoustically engineered design makes the Bryant HRV the quietest on the market and ensures that comfort is felt not heard Unlatching two 2 suitcase style latches allows easy removal of the filters and core for cleaning NOTE The HRV should not be installed in an attic or unconditioned space unless provisions are made for drainline freezing and condensation STANDARD FEATURES HRVBBSVA Energy saving defrost cycle Cross flow counterflow heat exchangers One filter on incoming air one filter on outgoing air

7. al heating and cooling load charts Although the ventilators process the outside air before it enters the home additional heating and cooling loads need to be considered The heating load chart shows the heating loads in BTUh for a range of winter design temperatures for each model of ventilator EXAMPLE The heating design temperature for Milwaukee WI is 4 F At 5 the additional heating load of the HRVBBLHA1250 is 8417 BTUh This additional load should be taken into consideration when sizing the heating equipment HRV COOLING LOAD BTU Cooling Load BTUh Inside Design Outside Temp 75 F and 50 Relative Humidity Enthalpy BTU Ib HRVBBLHA1150 HRVBBLHA1250 30 670 1 071 31 1 090 1 741 32 1 509 2411 33 1 928 3 080 34 2 347 3 750 35 2 766 4 419 36 3 185 5 089 37 3 604 5 759 38 4 023 6 428 39 4 442 7 098 40 4 861 7 767 41 5 280 8 437 42 5 699 9 107 The cooling load chart shows the loads in BTUh also To use the cooling load chart first find the design enthalpy from a psychrometric chart using the design dry bulb and wet bulb temperatures See following psychrometric chart The cooling load can then be found for a range of enthalpies for each ventilator EXAMPLE The cooling design dry bulb temperature for Milwaukee WI is 87 F and the average wet bulb at that temperature is 73 F On the psychrometric chart the enthalpy is about 37 7
