Embodiment 1

[0052] Example 1: Dual cold sources in parallel with four pipes and two-stage pump air-conditioning water system

[0053] Such as image 3 As shown, the air-conditioning cold source of the air-conditioning water system with two parallel cooling sources and four-pipe secondary pumps is composed of a high-temperature cooling source and a low-temperature cooling source, and the high-temperature cooling source and the low-temperature cooling source are connected in parallel; the high-temperature cooling source and the low-temperature cooling The sources are all cooled by cooling towers; the cooling water at the outlet of the cooling towers passes through the first cooling water pump CWPI and the second cooling water pump CWPII to provide cooling capacity for the high temperature cold source and the low temperature cold source respectively.

[0054] The supply water temperature of the high-temperature cold source is 10-16°C, the return water temperature is 15-21°C, and the temperat...

Embodiment 2

[0061] Example 2: Parallel connection of dual cold sources and four-pipeline primary pump air-conditioning water system

[0062] Such as Figure 4 As shown, different from Embodiment 1, in this system, only the primary pump is used as the fluid driving source. The high-temperature chilled water secondary pump unit HPII and the low-temperature chilled water secondary pump unit CPII are cancelled. The high-temperature chilled water first-stage pump unit HPI and the low-temperature chilled water first-stage pump unit CPI can use fixed-frequency pumps or variable-frequency pumps at the same time.

[0063] In this embodiment, the HPI of the high-temperature chilled water first-stage pump unit and the CPI of the low-temperature chilled water first-stage pump unit are frequency conversion ( Figure 4 is the structural schematic diagram of this embodiment), the second high-temperature bypass pipe HBPII between the high-temperature water supply pipe HSP and the high-temperature retur...

Abstract

The invention discloses a dual-cold source four-pipe-system air conditioner system. The dual-cold source four-pipe-system air conditioner system comprises air conditioner terminals provided with high-temperature surface cooling sections and low-temperature surface cooling sections and a cold source system for providing cooling capacity for the air conditioner terminals; the cold source system comprises a high-temperature cold source for providing the cooling capacity for the high-temperature surface cooling sections and a low-temperature cold source for providing the cooling capacity for the low-temperature surface cooling sections; the high-temperature cold source and the high-temperature surface cooling sections are connected through a high-temperature water supply pipeline provided with a high-temperature water segregator and a high-temperature water return pipeline provided with a high-temperature water collector; and the low-temperature cold source and the low-temperature surface cooling sections are connected through a low-temperature water supply pipeline provided with a low-temperature water segregator and a low-temperature water return pipeline provided with a low-temperature water collector. According to the dual-cold source four-pipe-system air conditioner system, under the precondition that the total capacity of a whole air conditioner water chilling unit is unchanged, the ratio of load borne by a high-temperature unit is increased to the greatest extent through reasonably allocating the ratio of the air conditioner load borne by the high-temperature unit and a low-temperature unit, so that the energy consumption of the cooling load of the whole air conditioner system is greatly lowered, and the air conditioner system is an energy-saving-type air conditioner system.

Description

technical field [0001] The invention belongs to the technical field of central air-conditioning design, and specifically designs an air-conditioning refrigerant system with two cold sources and four pipes. Background technique [0002] The central air-conditioning system can be divided into a two-pipe system and a four-pipe system according to the arrangement of the hot and cold pipes. The so-called two-pipe system refers to a system in which the cold and heat sources use the same set of water supply and return pipes to provide cold water or hot water for the coil of the terminal device. The so-called four-pipe system means that the cold and heat sources respectively pass through their respective water supply and return pipes, and the system that provides air-conditioning cold water and hot water for the cold coil and hot coil of the terminal device is called a four-pipe system. There are four delivery pipes in the system. road. [0003] The characteristics of the two-pipe...
