A differential thermostat is a crucial component in modern heating, ventilation, and air conditioning (HVAC) systems. It plays a pivotal role in maintaining indoor comfort and energy efficiency. In this article, we will delve into the concept, functionality, and advantages of a differential thermostat.
What is a Differential Thermostat? A differential thermostat, also known as a temperature differential controller or temperature differential switch, is an intelligent device designed to regulate the temperature difference between two points. In HVAC systems, it typically monitors the temperature differential between the supply and return air ducts. This control is essential for optimizing system performance. How Does a Differential Thermostat Work? The core function of a differential thermostat is to ensure that the HVAC system operates efficiently by maintaining a consistent temperature differential. Here’s how it works: Temperature Sensing:The differential thermostat has two temperature sensors, one placed in the supply duct (where the conditioned air is distributed) and the other in the return duct (where the air is collected after circulating through the building).
