Problems solved by technology

[0003]During the regulation process, since the temperature difference between the hot water provided and the user side is not high, the maximum water volume is limited by the pressure between the dry water supply pipe and the dry return pipe, and the user side It takes a long time for the indoor fan coil unit to start from the shutdown state until the room temperature reaches the set value. Long-term operation or early operation, which greatly increases energy consumption

Abstract

The invention belongs to the technical field of comprehensive energy, and particularly relates to a quick-heating central air conditioner water circulation control system. The system comprises a first water circulation system and a second water circulation system. The first water circulation system achieves water circulation among a dry water supply pipe, an indoor water supply pipe, an indoor fan coil, an indoor water return pipe and a dry water return pipe; and the second water circulation system is provided with an electric heating water tank, and achieves water circulation among the indoor water supply pipe, the indoor fan coil, the indoor water return pipe and the electric heating water tank. The quick-heating central air conditioner water circulation control system can be directly connected between an existing central air conditioner control system and the indoor fan coil in series, and the influence on normal operation of an existing central air conditioner is avoided; and in the working process, the indoor temperature can be rapidly increased through the second water circulation system, long-term operation of the system is not needed while good experience of a user is maintained, and the comprehensive energy utilization efficiency of the system is improved. The invention further discloses a quick-heating central air conditioner water circulation control method which has the same advantages.

Description

technical field [0001] The invention belongs to the technical field of comprehensive energy, and in particular relates to a central air-conditioning water cycle control system and control method for rapid temperature rise. Background technique [0002] At present, the central air conditioner under the heating condition provides hot water with a medium temperature of about 50 degrees Celsius to the indoor fan coil unit on the user side through the water supply pipeline and the return water pipeline. The water supply and return water volume of the fan coil unit can effectively control the temperature of the user side. [0003] During the control process, since the temperature difference between the hot water provided and the user side temperature is not high, the maximum water volume is limited by the pressure between the dry water supply pipe and the dry return water pipe. In this case, in order to ensure that the user side can quickly obtain a suitable temperature when need...
