EVAPORATION

OF

ICE

CUBES

(rop

Mount

& side-By-side

Moders)

Since

ice

cubes have a moisture

vapor

pressure

above them,

the vapor

is

constantly

being

picked

up

in the

dry air stream

and deposited

on

the

evaporator.

This

physical

change

known

as

"sublimation",

is the

changing

of a solid to

a vapor

without

going

through liquid

state. In

a

forced

air treezer

compartment,

this

action will

be readily

noticed

by a customer

who

does

not

use ice cubes

with regularity.

AIR

FLOW. FORCED

The

balance

between the

air flow

into the fresh

food

and Ireezer

compartments

is

an im-

portant

factor in

maintaining

proper

compartment

temperatures

in

a

forced

air

refrigeration

system.

A

baffle is used

to regulate

the

amount of

chilled

air directed

into

the fresh

food

compartment.

lf

a colder treezer

compartment temperature

is

desired,

the

baffle is

adjusted

so that less

air is directed

into the

fresh food

compartment.

This

causes

the

compressor

to

run longer

since the

compressor thermostat

sensing

element is

located

in the fresh

food

compartment.

Cold

air is

drawn through

the fin

and tube

evaporator

and

into

the

fan.

A

portion

of the

air

is

deflected

into the f

resh food

compartment

where

it

absorbs heat

and returns

to the

f in

and

tube

evaporator

through

ports

in the

top

of the fresh

food

compartment

Most

of the

air

moving

through the

fin

and tube

evaporator,

however,

is

blown through

the

freezer

air tun-

nel

and

circulated

throughout

the freezer

compartment

and back

across

the fin

and tube

evaporator

where

it starts

another

cycle.
