Product Description

一、Introduction

Industrial water chiller is the fifth generation product designed and developed by our company's technical personnel based on decades of design experience of medium and low temperature water chillers and the advanced technology of similar products at home and abroad. It has the characteristics of high efficiency, energy saving, environmental protection and high reliability.

The equipment can provide - 45 ℃ - 0 ℃ medium and low temperature carrier refrigerant, which is suitable for places with various cold source requirements, such as textile printing and dyeing, plastics, electroplating medicine, chemical industry, metallurgy, electronics, food and other industries in the production process, and can also be used as the cold source host of large cold storage and cold field.

Heat recovery products can provide 50 ℃ ~ 60 ℃ domestic hot water at the same time, which can save energy.

二、Application

* It can be used as process cold source host in steel, medicine, electronics, chemical industry, food and other industries, as well as in central air conditioning and other places with chilled water requirements.

* All kinds of refrigerators, freezers, fresh-keeping warehouses, various ultra-low-temperature refrigerators, experimental refrigerators, constant temperature warehouses and other cold storage projects.

 

三、Main design features

1. Independent refrigeration system design, the refrigeration system of multi head unit is relatively independent and does not interfere with each other

2. Y-△Star-TriangleStep-down Start

Under the minimum load (25%), the compressor of each refrigeration system can be started by reducing voltage from star to triangle, which can effectively reduce the starting current and impact on the power grid

3. Heat recovery technology of waste heat utilization

4. Through the particularity of the operation of the medium and low temperature refrigeration main engine, the control mode of frequency conversion of cooling water pump and fan is provided for the operation in winter and transition seasons, so as to ensure the safe and reliable operation of the equipment and save energy; or the evaporative condenser is used to save energy and solve the operation problems in winter

5. Application of high efficiency refrigeration compressor

The operation mode of imported semi closed screw compressor with economizer is adopted

6. Flexible control system

The automatic control of the equipment adopts the mode of man-machine interface + PLC controller + moulded case circuit breaker + AC contactor, of which the PLC controller is mainly made of German Siemens. Its internal program is compiled by our company, and the control function of the equipment can be adjusted according to the requirements of users.

7. A variety of refrigerants can be selected

According to the needs of users, glycol aqueous solution, alcohol, ternary mixed solution (40% ethylene glycol, 40% water, 20% ethanol) and other alcohol refrigerant can be used; the evaporator can also be designed according to the anti-corrosion requirements, and calcium chloride aqueous solution is used as the carrier refrigerant.

8. Application of environmental protection refrigerant

It can be applied to a variety of environmental protection refrigerants, such as hfc404a, hfc507a, etc., to meet the requirements of international environmental protection. The use of the secondary oil separator can be applied to a variety of environmental protection refrigerants, such as hfc404a, hfc507a, etc., meeting the requirements of international environmental protection.

9. Application of liquid injection technology

Due to the low evaporation pressure, large compression ratio, high exhaust temperature and large bearing load of industrial water chiller, the liquid refrigerant is introduced into the compression chamber of cooling compressor from the middle section to effectively reduce the exhaust temperature (no more than 105 ℃) and make the bearing well lubricated. The reliability of the product is improved.

10. Design features of reducing cold bridge of unit

The main refrigerant pipes of industrial water chillers are connected by copper pipes. The connection surface between the condenser and the evaporator is not more than 0.005, and the contact surface is padded with insulating rubber pad, and the evaporator is insulated as a whole, so as to reduce the cold bridge between the evaporator and the condenser to the greatest extent; at the same time, the insulation pad is also padded between the compressor foot and the evaporator bracket to prevent the evaporator from leaking to the compressor and improve the comprehensive efficiency.

11. Automatic / manual emergency switching

In order to ensure the continuous supply of process cold source, in case of touch screen failure, the emergency automatic / manual switch is enabled instead of button start / stop, which will not affect the production.

 

四、Technical parameter table (Refrigerant R22)

The following table is part of the company's industrial chiller model for your reference, the capacity of refrigerant R22 industrial chiller is from 55KW to 2200KW, if you want to know the specifications of other models, please feel free to contact us.

Remarks

1. The nominal working conditions of refrigerating capacity are as follows: inlet water temperature of condenser is 30 ° C, outlet water temperature is 35 ° C, inlet water temperature of evaporator is - 5 ° C, outlet water temperature is - 10 ° C.

2. Due to the change of flow rate caused by the change of service conditions, the diameter of the interface can be adjusted, and the flow rate is controlled from 1.5m/s to 2.5m/s.

3. The results show that the water flow of evaporator increases about 15% when glycol water solution is used as refrigerant, calcium chloride water solution is used as refrigerant, and 3% when sodium chloride solution is used as refrigerant

4. The outlet water temperature of evaporator is lower than - 30 ° C, so glycol aqueous solution is not recommended.
