For the past 15 years, our factories have been engaging in micro refrigeration solutions for microclimate environment and confined spaces. And MOIR, backed up by our factories, has had a great handle on the comprehensive knowledge ranging from [What the Mini Compressor Is ? ], [ What’s Small Cooling Systems?], [ How does the Small Cooling System?] to [ Why … ].
If your application needs a unique, high reliability, and compact refrigeration system, MOIR has the experience and technology to develop and manufacture a custom refrigeration system to meet your specific requirements and provide you with a distinct market advantage. And if you have any issue with the micro cooling or need any technical support, our well-trained veteran would get you covered.
MOIR focuses on working for mini dc compressors based on miniature refrigeration technology with years of experience. The rotary dc compressor is the heart of the refrigeration & air conditioning system, comparable to a human heart or a car engine. It raises the pressure and temperature of the refrigerant vapor by reducing its volume.
MOIR’s mini vapor compressor is a variable capacity DC Compressor driven by a drive board, with a cooling capacity of 100 watts(340Btu/h) to 500 watts. The driver can real-time update motor parameters via the frequency of a sine wave signal, with variable speeds ranging from 1,200rpm to 6,500rpm.
Our mini dc rotary compressor can be utilized in the applications of LBP, MBP, and HBP.
LBP (Low Back Pressure) indicates the range of low evaporating temperatures, typically -10°C down to -35°C or even -45°C. , applies to freezers, refrigerators, etc.
MBP (Medium Back Pressure) indicates the range of medium evaporating temperatures, typically -20°C up to 0°C., and generally applies to cold drink cabinets, milk coolers, etc.
HBP (High Back Pressure) indicates high evaporating temperatures, typically -5°C up to +15°C, and generally applies to air conditioners, dehumidifiers, heat pumps, etc.
Capillary or expansion valve is a throttling device of a kind, one of the essential parts of refrigeration and air conditioning systems to complete the cycle of refrigeration. It drops the pressure of the high-temperature, high-pressure liquid refrigerant that comes from the condenser, to allow expansion or phase change from a liquid to a vapor in the evaporator where it’s exposed to the heat source.
Normally, miniature DC compressors are used in mobile refrigeration systems. DC power is produced by batteries, car charging, solar panels, or an AC inverter power supply. MOIR compressors are available for 12V, 24V, and 48V power supply.
The refrigerant recharge must be from the high pressure end (condenser side).
Only high purity (above 99.9% or above 99.95% if possible) HFC-134a be allowed
There are 4 ways to adjust compressor speed.
0-5v Speed control
The above 4 ways, the most common way to control the compressor is through potentiometer (included) adjustment.
Normally, the selection of a compressor should be made according to the following system cooling characteristics and operating conditions:
Minimum evaporator temperature
Maximum condensing temperature
Refrigerant type
Ambient temperature
Cooling capacity
Electrical power available
Compressor and drive cooling
The drive board in MOIR cooling module is a variable speed drive. It allows the cooling capacity of the system to be adjusted by increasing or decreasing the compressor speed. The compressor drive board utilizes a user supplied 0-5VDC analog signal to set the compressor speed.
The base refrigeration system consists of a compressor, a condenser, an expansion valve, and an evaporator. It uses the phase change of R134a refrigerant which has high heat thermal conductivity and heat absorption capacity to efficiently cool heat sources to temperatures below the ambient air. The refrigerated technology is the same used in your home refrigerator, making the inside temp of your refrigerator lower than the space it places.

Proper maintenance of a Mini-Chilled Water Systems includes regular cleaning, inspection of components, and ensuring proper lubrication and coolant levels. It is also important to follow the manufacturer’s guidelines for maintenance and care to ensure optimal performance and longevity. Our water chiller is a ingerated subsystem and problem-free operation. Each system is hermetically sealed, charged and tested with our strigent process prior to shipment.
The lifespan of a liquid chiller cooling unit depends on various factors such as usage, maintenance, and quality of the components. Generally, a well-maintained and high-quality compact cooling modules can last for 10 years or more.
The power consumption of a mini chiller varies depending on the size, cooling capacity, and operating conditions. However, miniature liquid chillers are designed to be energy efficient and consume less power than other cooling solutions.
No. Compact liquid chiller modules are designed to operate quietly, making them ideal for use in noise-sensitive environments such as laboratories, clinic, school, and medical facilities. The noise level of our small cooling system is >50dB.
Yes, miniature liquid chiller modules can be used in conjunction with other cooling solutions, such as air-cooled heat exchangers, to provide a complete and efficient cooling system.
The main difference between air-cooled chillers and water-cooled chillers is the way they remove heat from the refrigerant.
Air-cooled chiller: uses air to remove heat from the refrigerant in the chiller. They are typically more energy efficient and easier to maintain, but may not be suitable for areas with high temperatures or poor air quality.
water-cooled chiller: uses water to remove heat from the refrigerant. They are more efficient at removing heat but require a separate cooling tower and more maintenance.
Direct expansion is known as a direct refrigerant system and dc condensing unit( DX system). The dc condensing unit is the world’s smallest micro refrigeration system however offers the highest heat transfer rates. It can be easily integrated into many final solutions that are compact, quiet, reliable, and low consumption.
The direct refrigeration system is a set of cooling units directly flowing refrigerant through the cold plate evaporator with the circulation being driven by the mini compressor. It does not use a secondary coolant, instead, the refrigerant absorbs heat directly at the heat source through contact the heat exchanger( cold plate).
The refrigerant circulating systems eliminated the need for water lines and pumps(sources of leaks and failure), thus eliminating downtime for maintenance and repairs to the user’s device. Direct expansion cooling simplifies the system configuration, minimizing the size and component count of the system, also, improving reliability with a longer lifespan of 90,000 hours. It is smaller, and lighter but offers the highest efficiency.
The direct expansion evaporator system can be used in various applications, including:
The DX cool units and chilled water are two ways of cooling systems used in HVAC systems.
DX systems: Use refrigerant to directly cool the air.
Chilled water system: Use water that is cooled by a refrigeration unit to cool the air
Both systems have their advantages and disadvantages depending on the specific needs of your applications.
The typical operating temperature range for a direct expansion refrigerant cooling system depends on the application and the specific requirements. Using MOIR miniature compressor technology, the direct expansion unit can operate at temperatures as low as -15°C (-40°F) or as high as 55°C (131°F).
