Integral air conditioner and terminal water system device

Abstract

The invention relates to an integral air conditioner and terminal water system device which comprises at least two groups of refrigeration mechanisms connected in parallel and a cooling mechanism; therefrigeration mechanisms comprise chilled water pipes, chilled water pumps, check valves and constant pressure water replenishing mechanisms; the cooling mechanism comprises at least two groups of cooling towers connected in parallel, control valves and fans; at least two groups of flow monitoring mechanisms and pressure regulating valves are connected in parallel between the refrigeration mechanisms and the cooling mechanisms; the cooling mechanism is connected with the flow monitoring devices and the cooling towers through return passages; and the integral air conditioner and terminal watersystem device further comprises an energy storing mechanism connected with the cooling mechanism and the terminals of air conditioners. Multiple groups of cooling towers are arranged to perform hydraulic regulation on a single or multiple refrigeration mechanisms, so that the application range of a system is enhanced; and the independent flow monitoring devices and the independent pressure regulation valves, which are connected with each refrigeration main body, are used to improve the refrigeration efficiency of the system. The refrigeration mechanisms form an integral structure, so that theconstruction fields can be reduced, and the cost is reduced.

Description

Technical field [0001] The invention relates to the field of refrigeration and heating, in particular to an integral air conditioner and terminal water system device. Background technique [0002] The water system of the water-cooled central air-conditioning system includes a cooling water system and a chilled water / hot water system. Generally, a single pipe is used, with frozen water circulating in summer and hot water circulating in winter. Air-cooled or air-cooled heat pump only includes refrigeration / hot water systems. The circulating water system is an important part of the central air conditioning system. [0003] The chilled water circulation system is composed of chilled pumps, indoor fans and chilled water pipelines. The low-temperature chilled water flowing out of the main engine evaporator is pressurized by the refrigeration pump and sent into the chilled water pipeline (outlet), enters the room for heat exchange, takes away the heat in the room, and finally returns to...

AI Technical Summary

Problems solved by technology

[0004] On the one hand, the operation of the chiller directly affects the temperature regulation effect of the terminal equipment, and a single cooling cycle may cause insufficient supply of water temperature or water pressure; on the other hand, the return water temperature of the terminal water system gradually increases, It will also cause a decrease in the operating efficiency of the host

In addition, in conventional engineering applications, each component of the air-conditioning water system needs to be installed one by one on site, which requires high professional requirements for technology, resulting in high installation costs
