What Powers a Heat Pump: The Complete Electrical Control Framework

The electrical control system of a heat pump is structured around six functional pathways: power supply, actuation, sensing, logic control, safety protection, and human–machine interaction.
Its core components include the main control PCB, transformer, control panel, signal wiring, multiple temperature and pressure sensors, AC contactors, electronic expansion‑valve drivers, thermal overload protectors, terminal blocks, and communication modules.
Working together, these elements enable energy dispatching, state monitoring, actuation control, and multi‑level protection, forming the “brain and nervous system” of the heat pump.

Pressure Buffer: The liquid receiver also absorbs fluid shocks caused by rapid ambient‑temperature swings or fast compressor speed changes, providing high‑side pressure buffering that stabilizes system pressure boundaries and keeps the heat pump operating safely and smoothly under complex conditions.

The liquid seal protection is achieved by extending the liquid outlet tube of the receiver down to the bottom of the vessel, ensuring that only pure liquid refrigerant enters the throttling device (such as an electronic expansion valve). This structural design effectively prevents flash gas from entering the or***ce, which would otherwise cause control oscillation, superheat instability, and deterioration of COP. As a result, the stability and precision of throttling control are significantly enhanced.

1. Dynamic Material Balance:
During winter heating and reverse-cycle defrosting, the roles of the heat exchangers in an air‑source heat pump are reversed, resulting in significant differences in the optimal refrigerant charge required under various operating conditions. The liquid receiver functions as a “refrigerant reservoir,” absorbing excess liquid refrigerant under low‑load conditions and releasing it when the load increases. This enables dynamic balancing of the circulating refrigerant mass and provides the system with high operational flexibility and adaptability.

The gas–liquid separator is used to remove any unev***rated liquid refrigerant entrained in the refrigerant v***r leaving the ev***rator, ensuring that only dry v***r enters the compressor and thereby preventing liquid refrigerant from causing liquid hammer damage.

The four-way valve consists of three major components: the pilot valve, the main valve, and the solenoid coil.

3. Main Valve (Actuator)
The main valve is the ex*****on component that actually switches the refrigerant flow path: it contains a spool that slides left and right, and its body connects to four copper tubes—E (compressor discharge), S (compressor suction), C (condenser/water‑side heat exchanger), and D (ev***rator/air‑side heat exchanger). Under the pressure differential created by the pilot valve, the spool shifts within the valve body, changing the connection pattern among the four ports and thereby switching the system between cooling and heating modes. As the final stage of the reversing chain, the main valve performs the actual refrigerant flow reversal.

The four-way valve consists of three major components: the pilot valve, the main valve, and the solenoid coil.

2. Pilot Valve (Commander)
The pilot valve is a miniature control valve and serves as the command center of the entire reversing mechanism: driven by the solenoid coil’s armature motion, it regulates the opening and closing of fine internal passages (capillary or***ces) to control the flow of high‑ and low‑pressure gas, thereby altering the pressure differential across the main valve spool and “commanding” its left‑right movement. The pilot valve solves the engineering challenge that the main spool is too heavy for the solenoid coil to move directly, enabling a pressure‑amplification chain in which a small electromagnetic force controls a small valve, the small valve adjusts the pressure differential, and the pressure differential drives the large spool—making reliable reversing possible.

The four-way valve consists of three major components: the pilot valve, the main valve, and the solenoid coil.
1. Solenoid Coil (Control Source)
The solenoid coil, acting as the control source, is the starting point of the reversing action and functions as the system’s electronic switch: it receives electrical signals from the control board, generates magnetic force to pull in the armature when energized, and releases it under spring force when de‑energized. Because the coil produces a magnetic force that is “weak but extremely fast‑responding,” it cannot directly move the heavy main valve spool; instead, it drives only the pilot valve, which creates a pressure differential to amplify the control effect and thereby indirectly actuates the main valve’s reversing movement.
