Log P-H Diagram Refrigeration https://lnkd.in/dRKFFFKm The thermodynamic processes in the refrigeration cycle are complex. Calculation using formulae and tables requires a considerable amount of effort due to the three different states of the refrigerant from liquid, boiling and gaseous. Therefore, for reasons of simplify cation, the log p-h diagram was introduced.

In refrigeration tech, heat exchangers are vital components. Plate heat exchangers, gaining traction lately, show promising development potential. Unlike traditional shell-and-tube types, refrigeration-specific plate exchangers offer distinct advantages alongside typical features. https://lnkd.in/eCue6Xyk

What is the difference between between CODES and STANDARDS in the ammonia industry: In the ammonia refrigeration industry, codes and standards play crucial roles in ensuring the safe design, installation, operation, and maintenance of ammonia refrigeration systems. Although the terms "codes" and "standards" are often used interchangeably, there are some key differences between them: 1. Codes: Codes are regulatory documents that are legally enforceable. They are developed and mandated by government authorities, such as federal, state, or local agencies. Codes establish minimum safety requirements that must be followed in the design, construction, installation, and operation of ammonia refrigeration systems. Violating code requirements can result in penalties or legal consequences. Examples of codes in the ammonia refrigeration industry include the International Mechanical Code (IMC) and the Occupational Safety and Health Administration (OSHA) regulations. 2. Standards: Standards, on the other hand, are voluntary documents developed by industry organizations, professional associations, or technical committees. They provide guidelines, best practices, and recommended procedures for the design, installation, operation, and maintenance of ammonia refrigeration systems. Standards are not legally enforceable unless they are referenced in a code or regulation. However, they are widely recognized and followed by industry professionals as a means to achieve safe and efficient system operation. Examples of standards in the ammonia refrigeration industry include the IIAR (International Institute of Ammonia Refrigeration) standards, such as IIAR 2 (Equipment, Design, and Installation of Ammonia Mechanical Refrigerating Systems) and IIAR 6 (Standard for Inspection, Testing, and Maintenance of Closed-Circuit Ammonia Refrigeration Systems). In summary, codes are mandatory regulations established by government authorities, while standards are voluntary guidelines developed by industry organizations. Compliance with codes is legally required, while adherence to standards is considered best practice. Both codes and standards are essential in ensuring the safe and efficient operation of ammonia refrigeration systems, with codes providing the legal framework and standards offering industry-accepted guidelines for system design, installation, operation, and maintenance.

U.S. OEM Zero Zone announced that it is offering 90bar (1305psi)-rated display cases and low-side system components for its transcritical #CO2 (R744) systems in order to reduce the frequency and impact of refrigeration safety relief events. The pressure rating in a #CO2system for cases and low-side components (everything from the outlet of the high-pressure expansion valve up to the outlet of the compressors) has traditionally been 45bar (653psi), which Zero Zone will continue to offer. High-side components continue to be rated at 130bar (1,885psi).

In a food facility, ammonia detectors should be strategically installed in areas where ammonia refrigeration systems are present or where ammonia leaks are most likely to occur. Here are some key locations to consider for installing ammonia detectors: 1. Machinery Rooms: Ammonia refrigeration systems are typically housed in machinery rooms. Install ammonia detectors in these rooms to quickly detect any leaks or releases of ammonia from the system. 2. Compressor Rooms: Ammonia compressors are a potential source of leaks. Install ammonia detectors in compressor rooms to monitor for any ammonia leaks from the compressors or associated equipment. 3. Refrigerated Rooms: Install ammonia detectors in refrigerated rooms or cold storage areas where ammonia is used as a refrigerant. These detectors will help identify any leaks that may occur within these spaces. 4. Pump Rooms: If there are pumps associated with the ammonia refrigeration system, consider installing ammonia detectors in pump rooms to monitor for leaks. 5. Pipe Chases and Ducts: Ammonia pipes and ductwork can be hidden within pipe chases or ducts. Installing ammonia detectors in these areas can help detect leaks that may occur in concealed spaces. 6. Ventilation Systems: Ammonia detectors should also be installed in the ventilation system of the facility. This allows for the early detection of any ammonia that may be released into the air and ensures prompt action can be taken to prevent further exposure. 7. Emergency Exits and Escape Routes: Install ammonia detectors near emergency exits and escape routes to ensure the safety of personnel during an ammonia leak or release. It is important to consult the IIAR-2 standard and any applicable local regulations or guidelines when determining the specific locations for ammonia detector installation. Additionally, it is recommended to work with a qualified professional who can assess the facility and provide guidance on the proper placement of ammonia detectors to ensure effective monitoring and safety.

A refrigeration capillary tube is a small, narrow tube that is used in refrigeration systems to control the flow of refrigerant. It is typically made of copper or other highly conductive metal, and is used in conjunction with a compressor, evaporator, and condenser to transfer heat from one location to another. The capillary tube is placed between the evaporator and ...
