This video uses a water stream to demonstrate how a thermostatic expansion valve (TXV) works. The TXV uses pressure differentials to control the amount of refrigerant flowing through the system, adjusting to changes in temperature and heat load. The video explains the different pressures involved and how they interact to regulate the refrigerant flow.

This video explores the operation and troubleshooting of an electric expansion valve (EEV) commonly found in VRF and mini-VRF systems. The video explains how the EEV uses a series of electrical pulses to control the flow of refrigerant, and demonstrates how to test the electrical resistance of the coils within the EEV.
