Embodiment 1

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

Embodiment 2

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

[0071] Such as figure 2 As shown, in this embodiment, the water supply variable temperature control system includes the water supply variable temperature control system including: load rate calculator J, outlet water temperature setter K, overtemperature room ratio calculator F, overtemperature room ratio controller G , a gain characteristic average calculator I, a gain controller H, an outlet water temperature calculator M, a 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 self-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 conditioning, 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 fan coil thermostat products mostly adjusts the wind speed according to the deviation between the actual temperature of the room and the room’s set temperature. Moderate temperature deviation adopts medium-speed windshield, and high temperature deviation adopts high-speed windshield. [0003] The existing air-conditioning temperature control system also has a type that can continuously adjust the wind speed or water supply volume, which can continuously adjust the fan speed or water supply volume according to the regional temperature to achieve temperature control. PID control algorithm is usually used. [0004]...
