HEATING APPLICATIONS

OBJECTIVES FOR SUPPLY OUTLET LOCATION:

INCREASING MEAN RADIANT TEMPERATURE (MRT).

REDUCE CONDENSATION.

PREVENT UNEVEN AIR TEMPERATURE DISTRIBUTION.

MIXING WARM AIR WITH COLD INFILTRATION AIR TO PREVENT CHILLY DRAFTS.

LOCATION OF RETURN INLETS IN HEATING ONLY APPLICATIONS:

NEAR THE FLOOR ON THE OPPOSITE SIDE OF THE ROOM FROM SUPPLY OUTLETS.


INTRODUCTION




LOCALIZED EXHAUST

SAMPLE QUESTIONS

HEATING ONLY APPLICATIONS

OBJECTIVES:DISCOURAGE STRATIFICATION OF COOL AIR NEAR THE FLOOR.

INSURE THAT AIR COVERS THE ENTIRE ROOM.


INTRODUCTION




LOCALIZED EXHAUST

SAMPLE QUESTIONS

RICHARD MEIER, ACKERBERG HOUSE, MALIBU, CA, 1984-1986

IN APPLICATIONS WHICH ARE PRIMARILY HEATING, BUT HAVE SOME COOLING REQUIREMENTS, SUPPLY OUTLETS ARE LOCATED LOW ON AN OUTSIDE WALL AND RETURNS ARE LOCATED HIGH ON AN INSIDE WALL.


INTRODUCTION




LOCALIZED EXHAUST

SAMPLE QUESTIONS

IF HEATING IS THE PRIMARILY LOAD, BUT SUMMER COOLING IS REQUIRED: RETURNS SHOULD BE LOCATED HIGH ON WALLS ON THE OPPOSITE SIDE OF THE ROOM FROM SUPPLY OUTLETS.

IN APPLICATIONS WHICH ARE PRIMARILY HEATING, BUT HAVE SOME COOLING REQUIREMENTS, SUPPLY OUTLETS ARE LOCATED LOW ON AN OUTSIDE WALL AND RETURNS ARE LOCATED HIGH ON AN INSIDE WALL.

CEILING DIFFUSERS


INTRODUCTION




LOCALIZED EXHAUST

SAMPLE QUESTIONS

CEILING DIFFUSERS

CEILING DIFFUSERS:PREVENTS UNEVEN AIR TEMPERATURE DISTRIBUTION.

PRIMARY AIR IS PROJECTED RADIALLY IN ALL DIRECTIONS RESULTING IN QUICK DIFFUSION.


INTRODUCTION




LOCALIZED EXHAUST

SAMPLE QUESTIONS

CEILING DIFFUSERS

COOLING APPLICATIONS:

CEILING DIFFUSERS ARE OFTEN USED IN RETAIL SHOPS WHERE CEILING HEIGHTS ARE RELATIVELY LOW AND COOLING IS THE DOMINATE LOAD. THIS ARRANGEMENT ALSO LEAVES THE FLOOR AREA FREE FOR MERCHANDISING.


INTRODUCTION

SAMPLE QUESTIONS

CEILING DIFFUSERS

COOLING APPLICATIONS:

CEILING DIFFUSERS ARE ALSO USED IN THE CORE AREA OF OFFICE BUILDINGS WHERE THE LOAD IS PRIMARILY COOLING AND AGAIN CEILING HEIGHTS ARE RELATIVELY LOW.

LOCALIZED EXHAUST

SAMPLE QUESTIONS

HIGH SIDE-WALL SUPPLY

OBJECTIVES:

INCREASING MEAN RADIANT TEMPERATURE (MRT).

REDUCE CONDENSATION.

PREVENT UNEVEN AIR TEMPERATURE DISTRIBUTION.

MIXING WARM AIR WITH COLD INFILTRATION AIR TO PREVENT CHILLY DRAFTS.


INTRODUCTION




LOCALIZED EXHAUST

SAMPLE QUESTIONS


HIGH SIDE-WALL LOCATIONS:

ALLOWS STRATIFICATION OF WARM AIR ABOVE OCCUPIED AREAS REDUCING ENERGY CONSUMPTION.

CAN CAUSE NOISE PROBLEMS IN QUIET BUILDINGS (AIR CAN ONLY BE THROWN QUIETLY ABOUT 30 FEET).

LOCALIZED EXHAUST

SAMPLE QUESTIONS

COMBINED HEATING & COOLING APPLICATIONS

COMBINED HEATING & COOLING APPLICATIONS:

SYSTEM DESIGNED TO THE DOMINATE LOAD DURING THE TIME OF OCCUPANCY.

BECAUSE IT IS EASIER TO BLOW WARM AIR DOWN (LESS DENSE) THAN IS TO BLOW COOL AIR UP, PREFERENCE IS GIVEN TO THE COOLING LOAD.
