Embodiment 1

[0020] Such as figure 1 As shown, a central air-conditioning system is composed of a main engine, a chilled water device, a terminal device, and an air-conditioning control system. If the main engine adopts a water-cooled cold (hot) water unit, it also includes a cooling water device. The function of the main engine is to provide cold (hot) water source needed for air conditioning, and its composition can be refrigeration equipment such as water chiller and lithium bromide absorption refrigeration unit. The function of the cooling water device is to transport the heat of the unit to the cooling tower and dissipate the heat into the air. It consists of a cooling water pump, a cooling water tower, pipelines, etc., and the cooling water tower is equipped with devices such as fans and water-cooled condensers. The chilled water device, whose function is to transport the chilled water of the unit to the air treatment equipment or the terminal, is a hydraulic pipeline device, includ...

Embodiment 2

[0104] The difference between this embodiment and the first embodiment lies in that the main engine adopts multiple chillers.

[0105] Such as Figure 5 As shown, the operating mode of the second embodiment is:

[0106] When the load of the air-conditioning system increases, the operating sequence of the air-conditioning host is as follows:

[0107] The first step: one machine runs with cold storage;

[0108] Step 2: One machine runs under high load;

[0109] The third step: two machines cold storage operation;

[0110] Step 4: The two machines run under high load;

[0111] Step 5: Three machines run in cold storage;

[0112] Step 6: The three machines are running under high load...

[0113] When the load of the air conditioner decreases, the operating sequence of the air conditioner is as follows:

[0114] Step 1: The three machines run under high load;

[0115] Step 2: The three machines are running in cold storage;

[0116] Step 3: The two machines run under high l...

Abstract

This invention relates to an energy-saving central air conditioning system, which comprises cold and hot water source host, terminal device and the control system to adjust and monitor. The said control system processes according to the large amount of data collected to get the needed optimized status operation orders. It real-time adjusts the each part load of the system into cold storage or cold discharging modes and the said host works under the mode of cold storage and stops working in cold discharging mode.

Description

technical field [0001] The invention relates to a central air-conditioning system, in particular to an energy-saving central air-conditioning system. Background technique [0002] With the rapid development of social economy, hotels, office buildings, large venues and other places using central air-conditioning systems are becoming more and more widespread. Since the design of the central air-conditioning system is mostly calculated and selected based on peak climate conditions and load capacity. In the actual operation of the system, with the change of season, time and the heat dissipation of the used space, the actual load is far lower than the design value most of the time throughout the year. Take hotels as an example: air-conditioning load generally includes: ① building envelope heat transfer (including solar radiation heat); ② lighting, refrigerators, kettles and other electrical appliances heat dissipation; ③ human body heat dissipation; ④ fresh air load and power eq...
