Project background:
Dehumidification air conditioning upgrade in the drying workshop of XX paper mill
Industry: Paper industry
Core needs:
The humidity in the workshop is >85% for a long time, resulting in unstable moisture content of paper;
The energy consumption of traditional dehumidifiers accounts for 25% of the total electricity consumption of the production line;
The demand for steam exhaust heat recovery is urgent.
Project background:
XX chemical plant explosion-proof workshop air conditioning system transformation
Industry: chemical manufacturing
Core requirements:
There are flammable and explosive gases in the workshop, which must meet ATEX explosion-proof certification;
Strong acid and alkaline gases corrode traditional air conditioning equipment;
The workshop temperature in summer can reach 50℃, affecting production safety.
Project Background:
XX Biopharmaceutical Workshop Sterile Environment Transformation
Industry: Biopharmaceutical
Core Requirements:
Air conditioning system must comply with FDA/GMP dynamic cleanliness standards;
Disinfection and sterilization shorten the life of traditional air conditioners;
There is a risk of cross contamination in the exhaust system.
Project background:
XX Textile Group Intelligent Constant Humidity Energy Saving Project
Industry: Textile Printing and Dyeing
Core requirements:
Humidity fluctuations in workshops lead to an increase in yarn breakage rate;
Electricity costs of traditional air conditioners account for 18% of production costs;
Cotton wool and dust clog the filter of traditional air conditioners.
Project background:
Dust-free air conditioning transformation of XX semiconductor factory
Industry: Electronic manufacturing
Core requirements:
Cleanliness must be maintained at ISO Class 5;
Humidity fluctuations lead to a decrease in chip yield;
24-hour uninterrupted operation with high reliability requirements.
Project background:
XX Steel Group rolling mill cooling project
Industry: steel smelting
Core requirements:
The workshop temperature often reaches above 45℃, affecting the safety of workers;
Traditional spray cooling causes equipment corrosion;
The waste heat of high-temperature flue gas needs to be recovered.
Project background:
Upgrade of high-efficiency air conditioning system in XX frozen food factory
Industry: Food processing
Core requirements:
Low-temperature workshop (-18℃) has high energy consumption and severe cooling loss;
Traditional air conditioning cannot meet HACCP hygiene standards;
Operation costs need to be reduced to cope with price competition in the industry.
Project background:
Customer name: XX Automobile Manufacturing Co., Ltd.
Industry: Automobile manufacturing
Plant scale: 200,000 square meters of floor space, 80,000 square meters of workshop area
Pain points:
The original traditional air-conditioning system has high energy consumption, and the electricity bill in summer accounts for more than 35% of the total energy consumption;
The temperature and humidity in the workshop fluctuate greatly, affecting the stability of the production process;
The carbon emission index does not meet the industry's environmental protection requirements, and green upgrades are urgently needed.
Project Background:
An electronic material production plant faces stringent environmental control requirements: the workshop needs to maintain constant temperature and humidity throughout the year, and at the same time, it needs to filter dust and chemical particles in the air to ensure the production quality of precision electronic components. Traditional central air-conditioning systems have high energy consumption, complex maintenance, and difficulty in meeting cleanliness requirements, becoming a bottleneck for enterprises to reduce costs and increase efficiency.
Project Background:
As a high-end brand of InterContinental Hotels Group focusing on personalized business travel, a hotel in Chengdu is located in the northern part of the central city, with the core concept of integrating modern design aesthetics with intelligent technology. The hotel needs to meet the needs of a 24-hour constant temperature and humidity environment, while taking into account energy saving and quiet effects, especially in functional scenes such as gyms, restaurants and conference areas, which puts higher requirements on the precise control and air quality of the air conditioning system. The high energy consumption and uneven air supply of traditional split air conditioners have become operational pain points, and a set of efficient, energy-saving and flexible solutions is urgently needed.
