Embodiment 1

[0028] Such as figure 1 As shown, this embodiment provides a water supply variable temperature control system based on terminal comfort, which can be used in a central air conditioning system. The central air-conditioning system consists of chillers and distributed in multiple zones (ie branch cooling areas, in figure 1 There are m partitions in multiple air conditioners, and each partition covers multiple rooms or multiple sub-areas (such as a large shopping mall, factory, etc., includes multiple sub-areas in a larger partition), each room or each sub-area At least one air conditioner is provided in the area. In the following description, a room is taken as an example for description. According to different actual application scenarios, a sub-area may also be used to replace the room in this embodiment. The chiller is used to output chilled water to each air conditioner, and the water output of the chiller is controlled through the total inverter pump P101, and then the cooling...

Embodiment 2

[0070] This embodiment provides a water supply variable temperature control system based on terminal comfort. In this embodiment, for the same parts as in Embodiment 1, the same reference numerals are attached and the description thereof is omitted.

[0071] Such as figure 2 As shown, in this embodiment, the water supply variable temperature control system includes a water supply variable temperature control system including: a load factor calculator J, an outlet water temperature setter K, an over-temperature room ratio calculator F, and an over-temperature room ratio controller G , Gain characteristic average calculator I, gain controller H, outlet water temperature calculator M, unit controller R, and multiple temperature control systems (not shown).

[0072] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the temperature control system in this embodiment includes: a gain auto-tuner E, a gain calculator O, and a temperature controller ...

Abstract

The invention discloses a water supply temperature-variable control system based on tail end comfort level and relates to the technical field of air conditioners. The water supply temperature-variable control system is used for solving the problem that a large-scale multi-zone air-conditioning system is difficult to meet the requirements of all the zones for the comfort level in all the time periods by adopting a traditional zone temperature control system or the energy waste exists. The water supply temperature-variable control system comprises a load rate calculator, a draining water temperature setter, an over-temperature room rate calculator, an over-temperature room rate controller, a plurality of temperature control systems, a gain feature averaging calculator, a gain controller, a draining water temperature calculator and a unit controller. The water supply temperature-variable control system provided by the invention is applied to a central air conditioner.

Description

Technical field [0001] The invention relates to the technical field of air conditioners, in particular to a water supply variable temperature control system based on terminal comfort. Background technique [0002] The existing air-conditioning temperature control system can adjust the room temperature by changing the wind speed gear. For example, the control mode of the fan coil thermostat product is mostly to adjust the wind speed according to the deviation between the actual room temperature and the room temperature setting, and the low-speed wind gear is used for small temperature deviations. Medium temperature deviation adopts medium speed windshield, high temperature deviation adopts high speed windshield. [0003] The existing air-conditioning temperature control system also has the type that can continuously adjust the wind speed or water supply volume. The fan speed or water supply volume can be continuously adjusted according to the regional temperature to achieve temperat...
