[0002] A cooling source system is a technical device in a power system that provides cooling. It can provide cooling capacity to buildings, ensure a comfortable indoor environment, and is widely used in various civil and industrial buildings. With the continuous improvement of building energy conservation requirements, the energy efficiency of air conditioning cooling source systems has become a core indicator for evaluating their energy-saving performance.

[0003] Existing testing devices suffer from problems such as low accuracy in operating condition simulation, incomplete parameter acquisition, and poor control coordination. They cannot meet the requirements of high-efficiency air conditioning cold source systems for "stable operating condition simulation + full parameter acquisition + automated energy efficiency assessment". For example, traditional devices have difficulty in accurately controlling environmental parameters such as temperature, humidity, and air pressure, resulting in large deviations between test results and actual operation. They lack multi-location and multi-type parameter acquisition, making it impossible to comprehensively evaluate system energy efficiency. Each module operates independently, making it difficult to coordinate the simulation of complex operating conditions (such as partial load and variable environmental parameter operating conditions), resulting in poor accuracy and low practicality.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Please refer to Figures 1 to 3 Example 1: This utility model proposes a building-integrated high-efficiency air conditioning cold source system energy efficiency level testing device, including: a chamber module 1, an environmental control module 2, a parameter acquisition module 3, and an air pressure balance module 4; the chamber module 1 consists of a test chamber 101 and a sealed chamber door 102, the sealed chamber door 102 being detachably and fixedly installed on the side of the test chamber 101; the environmental control module 2 includes a temperature control unit 201, which consists of a heating component, a compression refrigeration unit, a finned evaporator, and an axial flow fan, the temperature control unit 201 being connected to the air duct of the test chamber 101 through a pipe, and the temperature control unit 201 adjusting the temperature according to the set temperature if necessary. The heating element operates, and the axial flow fan circulates hot air. If cooling is required, the compressor refrigeration unit starts, the finned evaporator cools, and the axial flow fan circulates cold air, bringing the temperature inside the chamber close to the set value. The parameter acquisition module 3 includes a mounting bracket 301 and a temperature and humidity sensor 302. The mounting bracket 301 is vertically installed inside the test chamber 101, and the temperature and humidity sensor 302 is fixedly installed on the side of the mounting bracket 301. The air pressure balance module 4 consists of an air pressure regulating channel 401 and a pressure transmitter 402. The air pressure regulating channel 401 connects the inside of the test chamber 101 and the pressure transmitter 402, and the air pressure regulating channel 401 is equipped with an air pressure regulating valve.

[0020] The test chamber 101 has a cold source channel 1011 on its side, and the cold source channel 1011 is connected to the exhaust pipe of the air conditioning cold source system. The air conditioning cold source system, the environmental control module 2, the parameter acquisition module 3 and the air pressure balance module 4 are all electrically connected to the external control device.

[0021] The environmental control module 2 also includes a humidity control unit 202, which consists of a humidifier 2021 and a dehumidifier 2022. Both the humidifier 2021 and the dehumidifier 2022 are located inside the test chamber 101 and are connected to an external water source and a drainage pipe, respectively. During use, the humidity control unit 202 operates according to the set humidity. When the humidity is lower than the set value, the humidifier 2021 works to release water vapor to increase the humidity. When the humidity is higher than the set value, the dehumidifier 2022 runs to remove excess water vapor and maintain stable humidity.

[0022] Among them, there are three sets of temperature and humidity sensors 302, and the three sets of temperature and humidity sensors 302 are located at the bottom, middle and top of the test chamber 101 respectively. This design enables the parameter acquisition module 3 to accurately collect accurate temperature and humidity information of the internal environment of the test chamber 101, thereby improving the accuracy of the test structure.

[0023] The silo module 1 adopts a combination structure of stainless steel frame and insulation board. The insulation board is polyurethane insulation board with a thickness of not less than 50mm. The side of the sealed silo door 102 is provided with observation window 1021, and the observation window 1021 is made of double-layer hollow tempered glass. This design can suppress heat loss, achieve energy saving and ensure structural reliability. The situation inside the silo can be observed in real time through the observation window 1021. The double-layer hollow tempered glass design of the observation window 1021 can also isolate the hot and humid environment, combining safety protection and durability.

[0024] The working principle of this embodiment is as follows: Target operating parameters, including temperature, humidity, air pressure within the test chamber 101, and the operating mode of the air conditioning cooling system, are input via an external control device (touchscreen). The external control device sends parameter commands to the environmental control module 2, air pressure balance module 4, etc., initializing the operating status of each module. The temperature control unit 201 operates according to the set temperature. If heating is required, the heating element operates, and the axial flow fan circulates hot air. If cooling is required, the compressor refrigeration unit starts, the finned evaporator cools, and the axial flow fan circulates cold air, bringing the chamber temperature close to the set value. The humidity control unit 202 operates according to the set humidity. When the humidity is below the set value, the humidifier 2021 operates, releasing water vapor to increase humidity. When the humidity exceeds the set value, the dehumidifier 2022 operates to remove excess water vapor and maintain stable humidity. The air pressure balance module 4 monitors the air pressure inside the chamber through the pressure transmitter 402. The air pressure regulating valve automatically adjusts according to the monitoring data to stabilize the air pressure inside the chamber within the set range, ensuring the air pressure conditions of the test environment. The temperature and humidity sensor 302 of the parameter acquisition module 3 collects temperature and humidity data at different locations inside the chamber in real time. The pressure transmitter 402 of the air pressure balance module 4 collects air pressure data. The external control device synchronously collects the operating parameters of the air conditioning cold source system (such as power and air volume). Based on the collected data, the cooling capacity of the air conditioning cold source system is calculated through the principle of energy conservation and related formulas. Combined with the input power, the energy efficiency ratio is calculated to achieve energy efficiency rating.
