Problems solved by technology

Due to the existence of heat transfer temperature difference, there must be a certain heat transfer loss in scheme (1), and the intermediate heat exchanger also greatly increases the initial investment of the system
Solution (2) also has the disadvantage of large initial investment in the system
Even if the terminal equipment requires the same temperature, due to the equipment selection principle of the power centralized system (to meet the flow rate and head of the most unfavorable loop), the initial investment and operating costs of the system are very large

Embodiment 1

[0028] This embodiment provides a new type of air-conditioning water distribution system, including: air-conditioning water supply pipes, air-conditioning return water pipes, and N-level users. The return water pipe of the air conditioner is connected to the water outlet of the Nth level of users, and an auxiliary regulating pipe is provided between the previous level of users and the next level of users, where N≥2. In this embodiment, the first-level users are connected in series with the second-level users, ...the N-1th level users are connected in series with the N-th level users, and the return water of the first-level users flowing in the first return water pipe of the air conditioner is connected with the water supply pipe of the air conditioner The water supplied by the air conditioner is mixed to the temperature required by the second-level user, ... the return water of the N-1-th level user flowing in the N-1th return water pipe of the air conditioner is mixed with the...

Embodiment 2

[0035] On the basis of Example 1, such as figure 1 As shown, N=2 in this embodiment. The novel air-conditioning water distribution system of this embodiment includes an air-conditioning water supply pipe, an air-conditioning return pipe, a primary user, and a secondary user. The water inlet end of the air conditioner is connected to the water supply pipe of the air conditioner through the second water supply pipe of the air conditioner, and the return water pipe of the air conditioner is connected to the water outlet of the secondary user. There is an electric two-way valve installed on the regulating pipe and the auxiliary regulating pipe. The secondary users give priority to using the return water of the primary user. When the return water of the primary user is insufficient, the main water supply of the air conditioner is used as the water supply for the secondary user. . The electric two-way valve regulates the amount of return water in the auxiliary regulating pipe ente...

Embodiment 3

[0041] On the basis of embodiment 2, this embodiment discloses such as figure 2 and image 3 Air conditioning water system for primary users shown. Air-conditioning water systems for primary users such as figure 2 As shown, it includes: air conditioner water supply pipe, air conditioner primary return pipe, multiple load users installed in parallel, degasser and decontamination device for removing air bubbles and impurities in the water supply, and the degasser and decontamination device is arranged on the air conditioner water supply pipe; The air conditioner water supply pipe and the primary return water pipe of the air conditioner are respectively connected to each load user, so that the water supply in the air conditioner water supply pipe becomes return water after being used by the load user and then flows to the primary return water pipe of the air conditioner.

[0042]The degassing and decontaminating device provided in this embodiment is preferably a spiral degass...

Abstract

The invention provides a novel air conditioner water transportation and distribution system. The novel air conditioner water transportation and distribution system comprises an air conditioner water supply pipe, an air conditioner water return pipe and N level users. The water inlet end of each level user communicates with the air conditioner water supply pipe through a user water supply pipe of each level. The air conditioner water return pipe communicates with the water outlet end of the Nth-level user, and auxiliary regulating pipes are arranged between the former-level users and the latter-level users, wherein N is greater than or equal to 2. The first-level user is connected in series with the second-level user, and return water of the first-level user and supply water of the air conditioner water supply pipe are mixed into the temperature required by the second-level user. The novel air conditioner water transportation and distribution system can greatly reduce the energy consumption of cold and hot water transportation to improve the hydraulic stability of the system, and can reduce the initial investment and operating cost of the system.

Description

technical field [0001] The invention relates to the field of heating, ventilating and air-conditioning, in particular to a novel air-conditioning water transmission and distribution system. Background technique [0002] In the design of heating and cooling systems, the temperature of cold and hot water provided by the cold and heat source is not necessarily the appropriate temperature for the terminal equipment. It is likely to be 95°C or 110°C. At this time, it is necessary to reduce the temperature of the heat medium of the heat source before it can be used for the heating terminal equipment. When the water supply temperature of the cold and heat source does not match the demand of the terminal equipment, there are two traditional methods: (1) The cold and heat source and the terminal equipment are indirectly connected through heat exchange through an intermediate heat exchanger; (2) Two or more sets of pipe networks are set up The system meets the needs of different term...
