In modern industrial production, a temperature and humidity-controlled workshop is crucial for numerous industries such as manufacturing, electronics, and pharmaceuticals. The environmental conditions of temperature and humidity within the workshop directly impact the stability and reliability of product quality, as well as the efficiency of production. As air conditioning equipment is the core facility for maintaining this critical environment, the selection process cannot afford any mistakes.

One, Define Requirements

Confirm Humidity and Temperature Requirements Different manufacturing processes have varying requirements for temperature and humidity, such as in the production of electronic chips, where temperature control may be critical. The temperature is maintained at 22℃±1℃ with humidity ranging between 45%±5%; whereas, a typical printing workshop requires temperatures between 18℃-28℃ and humidity between 40%-70%. The specific production process dictates the required temperature and humidity ranges, as well as the control accuracy of fluctuations.

Consider the actual workshop conditions Measure and record the length, width, and height of the workshop to calculate its volume. Additionally, assess the workshop's sealing integrity, such as the airtightness of walls, doors, and windows, and determine if there will be frequent entry and exit of personnel and materials. These factors will influence the selection of air conditioning equipment and load calculations.

One, Focus on equipment performance parameters

1. Cooling and Heating Capacity: Based on a comprehensive assessment of factors such as the size and orientation of the workshop, local climate conditions, and heat generated during the production process, calculate the required cooling and heating capacities and select matching air conditioning equipment. An undersized unit may fail to achieve the desired temperature and humidity control, while an oversized one will increase investment and operational costs, potentially leading to frequent startups and shutdowns, which can impact the equipment's lifespan.

2. Dehumidification Capacity: If the workshop has high humidity control requirements, particularly under conditions with heavy moisture loads, such as during summer when a large amount of fresh air is introduced or moisture vapor is produced during the production process, it is crucial to pay close attention to whether the air conditioning equipment's dehumidification capacity meets the requirements. Refer to relevant formulas and enthalpy-humidity charts as tools for calculation and selection.

Airflow and Air Pressure Sufficient air supply ensures uniform air circulation and stable temperature and humidity distribution within the workshop. Additionally, it is crucial to consider whether the wind pressure meets the workshop's requirements for air supply distance and outlet arrangement to ensure effective delivery of air to every corner of the workshop.

3. Filtration Efficiency: For controlled environment rooms with cleanliness requirements, such as electronics, pharmaceuticals, and food industries, it is essential to select air conditioning equipment with high-efficiency filtration capabilities to effectively remove dust, bacteria, and other impurities from the air, meeting the room's air purification standards.

We emphasize equipment quality and brand reputation.

1. Choosing Renowned Brands: Renowned air conditioning equipment brands typically have advantages in technology development, production processes, and quality control, ensuring more reliable product quality and performance, as well as a longer lifespan. Brands like Carrier, Trane, and Daikin are highly recognized and well-reputed in the恒温恒湿 air conditioning field.

2. Review Quality Certifications: Confirm if the equipment has passed relevant quality certifications, such as ISO 9001 Quality Management System Certification and 3C Certification, which to some extent ensure the quality and safety of the products.

3. Inspection of Equipment Components: Gain insight into the brand and quality of key components used in the equipment, such as compressors, fans, humidifiers, sensors, etc. High-quality components can enhance the overall performance and stability of the equipment, like air conditioning units equipped with renowned brand compressors, which offer more reliable cooling effects and operational efficiency.

Consider energy efficiency and operational costs

1. Focus on Energy Efficiency Ratio: The Energy Efficiency Ratio (EER) is a crucial indicator for assessing the energy utilization efficiency of air conditioning equipment. A higher EER signifies that the equipment can achieve better cooling, heating, and dehumidification effects with lower energy consumption during operation, thereby reducing operational costs. New energy efficiency standards were introduced in 2025, so it's essential to check whether the equipment meets the new standards when making a purchase to avoid buying products with low energy efficiency.

2. Calculating Operational Costs: In addition to the initial investment cost of the equipment, it is also necessary to consider the operational costs, which include electricity, water bills, maintenance and maintenance expenses, and consumables replacement costs, among others. For example, choosing a variable speed unit can help reduce operational energy consumption to some extent; however, methods like steam humidification may involve the operational costs of equipment such as boilers.

IV. Supplier Qualification and Reputation Review

Review Supplier Qualifications: Suppliers must possess the necessary production licenses, business licenses, and other legal operating qualifications to ensure that the equipment they sell is genuine. Verification of the supplier's production license number and other information can be done through official channels such as the Industrial Product Production License Query System.

2. Assess Supplier Reputation: Evaluate the market reputation and word-of-mouth of suppliers. Inquire with companies in the same industry about their experience using the supplier's equipment, or review the supplier's ratings and complaints on relevant evaluation platforms. Choose suppliers with good reputations and excellent after-sales service for collaboration.

Section V: Conduct on-site operational tests and debugging

1. On-Site Testing Requirement: Prior to equipment procurement, suppliers are required to conduct on-site operational tests. They must provide detailed selection plans and equipment specifications based on the actual conditions of the workshop, along with a simulated operational test report that includes extreme temperature and humidity tests, noise level detection, and equipment vibration amplitude testing, to ensure the selected equipment meets the actual usage requirements of the workshop.

2. Participating in Equipment Commissioning: During the equipment installation and commissioning phase, we arranged for professional personnel to be involved. They familiarized themselves with the operation of the equipment and recorded and verified the various parameters during the commissioning process to ensure that the equipment operates smoothly and achieves the expected temperature and humidity control effects.
