Application of energy balance valve in heating system

Energy-saving heating and air-conditioning systems is one of the most important components of building energy efficiency. The balance valve is heating, refrigeration system, one of the key energy-saving equipment. The role of its key equipment is mainly reflected in the following areas: 1. The key components to achieve hydraulic balance of cold and hot water systems. 2. The actual operation of thousands of projects also proved that the balance valve is air-conditioning, heating system to improve energy efficiency, reduce energy consumption, reduce project cost to ensure safe, reliable operation, so that the system is one of the important equipment users are indispensable. 3. Balance valve is an important heating and air conditioning system billing an indispensable important equipment. With the continuous improvement of customer satisfaction, the market is more and more balanced valve. 1. Expand the scope. From megacities, large and medium-sized cities to small cities and small towns; from thermal companies and residential quarters to government agencies and colleges and plant sites; from heat supply and heating to air-conditioning systems; from south to Haikou to north to Harbin in different regions Different buildings, different levels of the use of the balance valve. 2. Heat companies, property management companies get benefits. After the balance valve, the heat company, property management company to achieve energy-saving operation, reducing heat consumption, power consumption, expanding the heating area. 3. The government departments concerned. The use of balanced valve heating, air conditioning system can be safe and reliable to ensure that users meet the indoor requirements, room temperature compliance rate, social benefits are very good, won the welcome of all levels of government.

Elevator Modernization

Elevator modernization (or lift modernisation) is the process of upgrading the critical parts of the elevator in order for it to be able to handle new technology, have better performance, improve safety, and even give the aesthetics an up-to-date appeal


Most elevators are built to provide about 20 years of service, as long as service intervals specified and periodic maintenance/inspections by the manufacturer are followed. As the elevator ages and equipment become increasingly difficult to find or replace, along with code changes and deteriorating ride performance, a complete overhaul of the elevator may be suggested to the building owners.

A typical modernization consists of controller equipment, electrical wiring and buttons, position indicators and direction arrows, hoist machines and motors (including door operators), and sometimes door hanger tracks. Rarely are car slings, rails, or other heavy structures changed. The cost of an elevator modernization can range greatly depending on which type of equipment is to be installed.

Modernization can greatly improve operational reliability by replacing mechanical relays and contacts with solid-state electronics. Ride quality can be improved by replacing motor-generator-based drive designs with Variable-Voltage, Variable Frequency (VVVF) drives, providing near-seamless acceleration and deceleration. Passenger safety is also improved by updating systems and equipment to conform to current codes.

Benefits of elevator modernization

Modernization can greatly improve operational reliability by replacing mechanical relays and contacts with solid-state electronics. Ride quality can be improved by replacing motor-generator-based drive designs with Variable-Voltage, Variable Frequency (VVVF) drives, providing near-seamless acceleration and deceleration. Passenger safety is also improved by updating systems and equipment (such as double brake system, unintended car movement protection device on the brake system etc.) to conform to current codes.
