Recommended Littelfuse Components for Heat Pumps
Accurate Temperature Sensing to Prevent Freezing Accurate Temperature Sensing to Prevent Freezing
Sensors are used to measure the refrigerant line temperature in a water source heat pumps. The HVAC system controller uses the sensors to maintain the refrigerant operating at optimum temperatures for efficiency and to prevent freezing refrigerant lines. Littelfuse sensors provide very fast temperature sensing. Littelfuse engineers worked with the customer to design a unique assembly shape, custom lead lengths and labeling to ease manufacturing integration.
