Is Hitachi air-conditioning compressor Toshiba brand

"I obviously bought a Hitachi air conditioner. It was discovered that the air conditioner used a Toshiba compressor during maintenance." A few days ago, some media reported this complaint about Hitachi air conditioners. Therefore, many consumers questioned the difference between the case and the internal machine brand: the purchase clearly identified a certain brand, why did you change the brand of the contents inside without telling it? Is there any difference between the products of the two brands? What if the after-sales service is not guaranteed?

Basic knowledge of refrigeration compressor (technology sharing)

Compressor, a driven fluid machine that promotes low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges the high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. Compression → condensation (heat release) → expansion → evaporation (heat absorption) refrigeration cycle.

Working principle of steam compressor_steam compressor application

Working principle of steam compressor_steam compressor application Working principle of steam compressor After the steam is filtered by the filter, clean steam then enters the host cavity through the intake valve, and the volume of the cavity changes from large to small to compress the steam. The volume of the cavity is changed by the rotor rotating under the drive of the motor. <img src="{{media url=&quot;Working_principle_of_steam_compressor_steam_compressor_application.jpg&quot;}}" alt="" />

16 Common Faults and Troubleshooting Methods of Cold Storage Refrigeration Equipment

[Fault analysis] After the refrigerant leaks in the system, the cooling capacity is insufficient, the suction and discharge pressures are low, and a much larger intermittent "squeaking" airflow sound can be heard at the expansion valve than usual.

How to prevent fire and explosion of compressors with lubricant

How to prevent fire and explosion of compressors with lubricant Cars driving at high speeds on the roads are extremely dangerous in the event of an accident. In severe cases, they will cause the car to explode. Why? It is precisely because the car contains gasoline. After violent collision and friction, the gasoline will ignite and detonate.
