Hitachi DC Variable Frequency Compressor DC65PHDG-D1Y2 DC80PHDG-D1Y2 DD94PHDG-D1Y2

It is a scroll compressor produced by Hitachi, suitable for air conditioning, heat pumps, and industrial, agricultural, and commercial refrigeration systems.
This compressor has the following characteristics and parameters:
1. Wide applicability: Suitable for commercial air conditioners of brands such as Midea, Gree, Zhigao, Haier, Hitachi, etc.
2. Stable operation: Whether using refrigerant R22 or new chlorine free refrigerants R134a, R404A, R507A, and R407C, they can operate smoothly and reliably.
3. Safety protection measures: Safety relief valves are installed between the high and low pressure chambers, and PTC temperature sensors are directly inserted into the exhaust chamber of the cylinder block. The motor protection adopts the PTC motor protector from KRIWAN company in Germany, and is equipped with a delay circuit to control the compressor to stop for 5 minutes before starting, effectively protecting the compressor.
4. High energy efficiency ratio: Energy regulation devices can be installed to achieve energy efficiency ratios at both partial and full loads

Product Description

Hitachi's scroll compressor adopts high-efficiency scroll technology and holds a patent for the world's first scroll air conditioning compressor.

Its characteristics include:

Efficient and energy-saving: Adopting a new driving mechanism to prevent excess refrigeration oil from causing a decrease in capacity in the refrigeration cycle, thus improving efficiency.

Anti over compression technology: ensures that the condensation pressure is not too high, avoids increased power consumption, and makes the refrigeration system more stable and reliable. ‌

Stepless frequency conversion technology: The compressor can start from 0Hz to the highest operating frequency, and the operating speed can be continuously and freely adjusted according to changes in system capacity.

Oil control technology: Two stage oil separation technology improves the reliability of the system. Design features: Asymmetric scroll design and reinforced bearing structure further improve the efficiency and service life of the compressor
