11. Differential temperature

When chamber temperature is equal or higher than set temperature, it allows compressor to

activate. When chamber temperature is equal or lower than set temperature – 0.6㷄, compressor will be inoperative.

12. Remote alarm

In normal operation : Remote alarm contact is opened In alarm or power failure : Remote alarm contact is closed

13. Solenoid valve

Solenoid valve is a magnetic valve which transfers gas to capillary tube that is located in the

center of evaporator.

(1) In condition that -18㷄҈SV (set temperature) 㻡-25㷄;

Solenoid valve will forcibly inactivate when PV (chamber temperature) - SV (set temperature) +5㷄 ҈ 0

Ex. 1) SV(set temperature): -20㷄 PV(chamber temperature): -10㷄 (-10) – (-20) + 5 = 15 ……15 is higher than 0 => Solenoid valve inactivates forcibly

2) SV(set temperature): -20㷄 PV(chamber temperature): -30㷄 (-30) – (-20) + 5 = -5 …… -5 is lower than 0 => Solenoid valve activates

(2) Diagnosis value for valve operation Solenoid valve is controlled with every 30 minutes by comparing diagnosis value with

SV(set temperature). The comparison is done after 1 minute elapses since the unit was started.

In condition that AT(ambient temperature) 㻡18.0㷄, diagnosis value is -40.0㷄.

In condition that AT(ambient temperature) 䋾18.0㷄, diagnosis value is 0.6 x AT(ambient

temperature) – 51

In condition that AT(ambient temperature) 㻢 diagnosis value, solenoid valve is linked

with compressor. That is, solenoid valve transfers gas to the capillary tube when compressor activates.

Ex. 1) AT(ambient temperature): 15㷄 SV(set temperature): -40㷄 Diagnosis value is -40.0㷄.

AT(ambient temperature) is higher than -40㷄(diagnosis value) so solenoid valve links with compressor.

2) AT(ambient temperature): 20㷄 SV(set temperature): -35㷄 Diagnosis value is 0.6 x 20(AT) – 51 = -39 Diagnosis value (-39) is lower than -35(diagnosis value) so solenoid valve links

with compressor.

3) AT(ambient temperature): 35㷄 SV(set temperature): -35㷄 Diagnosis value is 0.6 x 35(AT) – 51 = -30 Diagnosis value (-30) is higher than -35(set temperature) so solenoid value does

not link with compressor. That is, solenoid valve does not transfer gas to the capillary tube.

(3) Summary In condition of (1) (ambient temperature is equal or higher than set temperature + 6㷄),

solenoid valve forcibly activates.

In condition of (2), solenoid valve is controlled by diagnosis value to enable unit to reach

set temperature if both of capillary tube are used in high ambient temperature.

Solenoid valve is used to control chamber temperature uniformity in condition of higher

set temperature and to enable unit to reach set temperature in condition of higher ambient temperature.
