TestEquity 101H Temperature/Humidity Chamber 

Dehumidification is accomplished through Capillary Tube (10) and the copper lines which are 

bonded to the MTVG. The F4T Controller cycles the dehumidify coil liquid-line solenoid valve 

(SV2, 7/8) ON/OFF through SSR3 to control the amount of dehumidification by condensing 

moisture from the air. The moisture is condensed within the vertical space inside the MTVG. 

 

The hot gas regulator (5) is adjusted to keep the suction pressure at 8 PSIG when both SV1 and 

SV2 are off. A suction line cooling thermostatic expansion valve (6) senses the suction line 

temperature and injects liquid refrigerant to cool the suction return gas within safe limits.
