Industry knowledge
Other Chillers is an important product series developed by Zhejiang Kaidi Refrigeration Equipment Co., Ltd. (hereinafter referred to as Kaidi) with nearly 30 years of experience in the refrigeration field. It covers various types of refrigeration equipment such as scroll, piston, and centrifugal chillers. Its core function is to achieve heat transfer through the evaporation, compression, condensation, and throttling cycle of refrigerants, providing a stable cold source for industrial production and commercial scenarios. As the core component of the refrigeration system, Other Chillers have the common characteristics of adapting to different cooling capacity requirements, excellent operating energy efficiency, and wide application scenarios. With a complete R&D, production and service system, Kaidi has maintained a high reputation for this product series in the global market.

Product Principles and Core Types

Basic Refrigeration Principle

All Other Chillers operate based on the vapor compression refrigeration cycle: the refrigerant absorbs heat from chilled water in the evaporator and evaporates into gas. After being compressed and heated by the compressor, it releases heat in the condenser and condenses into liquid. Then it is depressurized and cooled through the throttling device before re-entering the evaporator, forming a continuous refrigeration cycle. As the core component, the performance of the compressor directly determines the COP value (refrigeration power/input power) of the unit. Through precision CNC machining and rigorous laboratory testing, Kaidi has improved the operating efficiency of the compressor by more than 15%.

Core Product Types and Characteristics

Product Type Core Structure Cooling Capacity Range Key Advantages
Scroll Other Chillers Twin scroll disk meshing compression 58-1163kW Low operating noise, small vibration, compact structure
Screw Other Chillers Twin screw rotor compression 121-3489kW High reliability, wide cooling capacity adjustment range
Centrifugal Other Chillers High-speed impeller compression 1055-35160kW Large cooling capacity, outstanding energy efficiency ratio
Lithium Bromide Absorption Other Chillers Absorption-regeneration cycle Customized on demand Suitable for waste heat utilization scenarios, strong environmental friendliness

Application Cases and Scenario Adaptation

The applications of Other Chillers cover multiple fields such as industrial production, commercial buildings, and data centers. Kaidi provides localized solutions relying on its global service network:
  • Data Center Scenario: Supplied centrifugal Other Chillers for a large-scale AI data center, adapting to the power demand of more than 50kW per cabinet, reducing the PUE value to below 1.2, and saving 40% of energy consumption annually. Relying on the technical support of the Shanghai Hongqiao R&D Center, the unit can realize 7×24-hour continuous operation monitoring.
  • Industrial Production Scenario: Equipped screw Other Chillers for an auto parts factory, accurately controlling the temperature of the production workshop at 20±2℃, with the stable output error of cooling capacity ≤ 3%, ensuring the precision of precision machining.
  • Commercial Building Scenario: Provided scroll Other Chillers for chain hotels, optimized the pipeline design combined with the hotel space layout, with the operating noise lower than 45dB, and reduced the installation space occupation by 30%.
  • Special Scenario Adaptation: Offered lithium bromide absorption Other Chillers for chemical industrial parks, using industrial waste heat to drive refrigeration, achieving dual goals of environmental protection and energy saving. The project was completed with localized commissioning through Kaidi Beijing Branch.

Frequently Asked Questions (FAQ)

  1. How to select the cooling capacity of Other Chillers?
    It is necessary to calculate based on actual cooling demand (unit: kW), ambient temperature, operating time and other parameters. Kaidi provides professional pre-sales program design services, and accurately matches models through load calculation software to avoid over-sizing or under-sizing.
  2. What should I do if an oil pressure alarm occurs during unit operation?
    First, check whether the oil level is sufficient. If the oil level is normal, check whether the oil filter is clogged. For long-term low-load operation, adjust the working condition to full-load state. Kaidi's after-sales team can provide remote fault diagnosis and on-site parts replacement if necessary.
  3. How to choose different refrigerant types?
    R134a and other environmentally friendly refrigerants (no ozone layer depletion risk) are recommended for conventional scenarios, and customized refrigerant solutions are available for special industrial scenarios. All Kaidi products comply with international environmental protection standards, and provide refrigerant recovery and refueling guidance.
