High Temperature Screw Heat Pump

System Design

These High Temperature Screw Heat Pumps are systematically optimized for high-temperature operation during the design phase: the refrigerant circulation path is more stable, the internal pressure distribution is more balanced, and key components always operate within a reasonable range.

It can maintain high-temperature output for a long time, making it more suitable for continuous operation scenarios.

Screw Structure

Screw structures have several inherent advantages in high-temperature applications:

Continuous compression process, resulting in smoother operation

Uniform internal stress, suitable for prolonged full-load operation

Stronger adaptability to changing operating conditions

In high-temperature hot water, heat recovery, and industrial heating fields, High Temperature Screw Heat Pumps are not a high-end option, but rather a safer and more mature choice.

From a structural design perspective, the unit optimizes the evaporation and condensation processes, allowing the refrigerant to fully participate in heat exchange within the heat exchanger, thereby reducing ineffective energy loss.

Installation

The settings within the box are the factory default configuration.

The dotted line box indicates settings that can be customized by the customer.

1) The power lines (three-phase five-wire) from the customer's distribution cabinet to the power cabinet, as well as the specifications and diameters of the wires, are specified in the electrical parameter table. (The wiring should be configured by the customer themselves.)

2) The power inlet and outlet method of the power cabinet is from the top and then out.

1) The power lines (three-phase five-wire) from the customer's distribution cabinet to the power cabinet, as well as the specifications and diameters of the wires, are specified in the electrical parameter table. (The wiring should be configured by the customer themselves.)

2) The power inlet and outlet method of the power cabinet is from the top and then out.

Electrical Parameter Table

Single compressor unit

Note: The circuit breaker is to be selected by the customer. Please use a motor protection type circuit breaker. Single-unit users require one power supply line, and dual-unit users require two power supply lines. The above electrical parameters are theoretical calculated values; please refer to the actual parameters.

Dual compressor unit

Note: The circuit breaker is to be selected by the customer. Please use a motor protection type circuit breaker. Single-unit users require one power supply line, and dual-unit users require two power supply lines. The above electrical parameters are theoretical calculated values; please refer to the actual parameters.
