The air can make the hot water supply system
In water supply system, centralized hot water supply system is widely applied in its composition, described below. As shown in Figure 3 as shown in Figure L, generally by the first circulation system, second circulation system and control accessories centralized hot water supply system.
L first cycle system
The first cycle system is also called the heat medium system, composed of a boiler, water heater and heat pipe network. The boiler to generate steam (or water) to the water heater through the hot medium pipeline, the radiating surface heating cold water, steam condensing into water, depending on the residual pressure by trap flows to the condensation water tank, then through a circulating pump back to the boiler to generate steam, so the cycle to complete hot water preparation.
2 second circulation system
Second circulation system is also called the hot water distribution system, is composed of a hot water distribution network and a return pipe network C is heated to the temperature of hot water. The design from the water heater outlet through a water distribution network to send to each hot water, and water heater for cold water from the water tank or water supply networks to meet the hot water; point at any time to meet the design requirements of water should be in only, level in the pipe and water pipe is arranged on the return pipe, so that a certain amount of water flow in the water distribution network and the water pipe network, U compensation for water distribution network to ensure the heat loss, water distribution point temperature of C according to the requirement of building and the nature of the use, can use the hot water supply mode;
(1) water supply cycle refers to the hot water supply system of bovine hot water distribution network of horizontal pipe, vertical pipe, even water distribution tube are not circulating pipeline. The system design of circulating water pump, water does not exist when the water phase waiting time before use, suitable for high-grade hotels, hotel senior residential high standard architecture, as shown in Figure 3 - 2 shows o
(2) semi circulating hot water supply mode refers to the water supply system is now only in hot water distribution network level ten pipe circulating pipeline, the way more than full-time and timing water supply construction, as shown in Figure 3 - 3 shows. (3) not circulating hot water supply mode refers to the hot water supply system water distribution network of the horizontal pipe, vertical pipe, water distribution pipes are not set up any circular pipe, application timing water supply system for small water supply system and the use of less demanding or continuous water systems, such as public bathroom, laundry etc., as shown in Figure 3 - 4 shows.
3 control accessories
The need for centralized hot water supply system control, connection, air and water temperature change, control and safety accessories used with automatic temperature regulator, trap, decompression Yan, safety valve, Peng Zhangyao (box), pipeline compensator, valve, water head, automatic exhaust valve C |
