    Air conditioners provide cooling in hot summers and warmth in cold winters. What components detect temperature within air conditioners? This article introduces temperature sensors, the key components for temperature detection in air conditioning units.

    There are generally two types of temperature sensors used in indoor air conditioner units. One type features an epoxy-encapsulated head, while the other utilizes a metal sleeve encapsulated head. Each type serves different functions.

    The epoxy-encapsulated temperature sensor primarily detects indoor temperatures in air conditioner units. It triggers the compressor to start when the indoor temperature rises above the user-set temperature, and stops it once the desired temperature is reached.

    On the other hand, the metal sleeve encapsulated temperature sensor monitors the evaporator in the air conditioner unit. It safeguards against malfunctions or abnormal temperatures in cooling mode. For instance, if the evaporator's temperature drops too low or frost begins to form, the air conditioner activates a protective mode. This sensor also serves as a crucial indicator for initiating defrost cycles during cooling operations.

    Under normal conditions, both sensors on the same unit should exhibit similar resistance, typically around 10KΩ at normal temperatures. Deviations from this resistance level may indicate sensor damage, necessitating replacement.
