Keeping heat pumps operating at peak efficiency ensures the comfort of building occupants and saves money. Consult this block diagram to identify Littelfuse components that help achieve those goals. Options include capacitors for motor starters, thermistors for temperature sensing, and TVS diode arrays for lightning protection. We also supply ESD suppressors for wireless interfaces.
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.
