  • China ventilation system underground mine | hstarschiller.com
    China ventilation system underground mine | hstarschiller.com
    1 Project Overview Ventilation system underground mine project is located in Yantai City, Shandong Province. It is a gold mining project for China National Gold Group Co., Ltd. The mine depth is 1500 meters. The temperature of the surrounding rock at the working face is expected to reach 43°C when the shaft reaches the bottom, and the temperature of the working face is required to be maintained at 25-28°C. 2. Ventilation requirements for underground mines Project Category Working space shaft of a well net diameter Ventilation parameters Air volume Number of operations Auxiliary shaft 50 meters 8.2 meter 8 times/h 21000 m3/h 8~10 people 3 Underground mine ventilation systems-- project design focus (1) Heavy load, high temperature, high humidity, (2) Poor environment, dust flying around the mine; (3) Long mine roadway, high system pressure, large cooling loss; (4) Fresh air circulation, large temperature difference; (5) The working conditions of the mining level change greatly in each period; (6) The wind speed of the mining face is difficult to control, and the wind speed is too low, and the phenomenon of harmful and toxic gas stratification is easy to occur. If the wind speed is too high, it is easy to cause dust flying and cause secondary pollution. 4 scheme design The design principle considers the customer's investment cost, delivery time, cost performance, safety and stability. The system is supplied with a complete set of equipment. The refrigeration section, the surface cooling section, and the air supply section are made into a skid model in the factory. It can be used after the on-site positioning, which greatly shortens the delivery time, reduces on-site installation costs, and reduces investment costs. 5. Project configuration Device name Cooling capacity Cooling power Air volume Supply air dynamic pressure Remarks Special refrigeration skid for mine 600kw 165kw 21000m3/h 7500pa Full fresh air 6. Program advantages (1) The whole set of equipment is produced and installed in the factory, shortening the delivery time and installation cycle; (2) The equipment is debugged in the factory to ensure reliable operation of the equipment ; (3) The integrated equipment can reduce the initial investment cost (civil construction and installation costs) ); (4) The equipment is cost-effective and has a high utilization rate. After the project is completed, it can be used for other projects; (5) The three-level meter cools down and the air outlet temperature is lower; (6) The system is designed with double vents, adopted in transition seasons and winter Fresh air is supplied to reduce operating costs. 7. Advantages of ventilation system in mining A. High efficiency and energy saving, matching the efficient flooded type heat exchanger produced by H.Stars Group. The chiller COP is as high as: 3.3 B. Reliable operation, adopting Hanbell high-efficiency compressor, high compression ratio, high energy efficiency, stable performance, multi-level energy adjus...

    From the perspective of market competition, the selection of special
    From a design perspective, look at the special "intelligence" of the H.Stars Group. This issue talks about the choice of compressor type. According to conventional thinking, there is not much difficulty in the selection of compressor types, scroll compressors for small units, screw compressors for medium-sized units, and centrifugal compressors for large-scale units. Why mention the choice of compressor type? Let's make a simulation selection, assuming that a water-cooled chiller of about 300kW is needed. Choose screw compressor, 40STD-280WS4, cooling capacity of 284kW, the price is about USD$ 1,4w. Choose scroll machine, 20STB-100WFO4, refrigeration capacity 300kW, the price is about USD$ 1,2w. From the data, the cooling capacity of the scroll machine is 6% larger than that of the screw machine, and the price of the scroll machine is 14% lower than that of the screw machine. I believe you already know which product is competitive. The same is true for air-cooled chillers, so I won’t give an example here. The following introduces the overlap area of the cooling capacity of the scroll machine and the screw machine. Looking at the manual, you can see that the cooling capacity of a single scroll unit can reach 300kW. The minimum cooling capacity of a single screw unit is 90kW. It can be seen from this that the cooling capacity of a single unit ranges from 90kW to 300kW where the scroll and screw overlap. In the future, everyone will encounter projects with a single unit cooling capacity ranging from 90kW to 300kW, and you can choose between scroll and screw flexibly.

  • H.Stars Group condensing units improve the food processing industry
    H.Stars Group condensing units improve the food processing industry
    Project Overview 1. This project is a cold storage project of a foreign-invested food company in Zhongshan, China. The project includes a 6T / secondary freezing warehouse (-35 ℃), a finished product warehouse, a raw material warehouse, a rolling room and a production workshop. 2. Equipment configuration description: The quick-freezing warehouse of this project adopts an H.Stars Group low-temperature single-compressor dual-stage condensing unit (the condensation equipment is equipped with an evaporative condenser), and the evaporator of the quick-freezing warehouse adopts a variable-pitch vertical cooler. Other cold storage uses a combination of one-to-one air-cooled condensing unit and ceiling-mounted chiller. Project advantages 1. The quick-freezing warehouse uses a single-compressor dual-stage condensing unit. The screw single-compressor dual-stage compression refrigeration cycle has a reduced pressure ratio per stage, less leakage, and less insulation loss; high volumetric efficiency and large cooling capacity; the intercooler is overcooled, which makes the cooling capacity Increased, improved refrigeration factor; rotor bearing with low stress and long service life; high thermal insulation efficiency, motor power saving, energy saving, easy to realize automatic control; 2. The heat recovery function of the condensing unit of the quick-freezing warehouse is provided to provide free hot water washing for the workshop; 3. By transforming the evaporative condenser storage tank into a frost water pool, the frost water and condensate water are mixed to realize the recovery of cold and heat energy, which not only improves the condensation effect of the quick-freezing condensing unit, but also guarantees several times. The temperature of frosting water will not be too low after circulation; 4. The water flushing system of this project recovers the frosting water for the evaporative condenser, which not only achieves the effect of saving water, but also solves the problems of cleanliness and temperature of the flushing water (the conventional water flushing system needs to be discharged regularly) Partly flush the frost water and add tap water) 5. Other cold storage condensation units and chillers use one corresponding method; the system is safe and reliable; 6. The evaporative condenser is used for the condensation equipment of the quick-freezing warehouse, which has large air volume and good heat dissipation effect. 7. The entire project adopts a centralized monitoring system, which is simple to operate, monitors the temperature of the cold storage at anytime and anywhere, and has a cold storage failure alarm function.
