Problems solved by technology
In such a situation, it is necessary to spend a lot of money on renting a dummy load, and a large amount of electric energy is consumed during the test, resulting in a serious waste of energy; and in order to obtain the chilled water temperature required by the chiller, it is necessary to frequently adjust the power of the terminal dummy load. Complicated and slow to respond

Embodiment Construction
[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0021] see figure 1 , which illustrates a schematic structural diagram of a system for on-load testing of chillers according to an embodiment of the present invention, the system may include:
[0022] Cooling equipment, freezing equipment, chillers to be tested and heat exchangers for water-to-water heat exchange,
[0023] Wherein, in the cooling water (Q) flowing out of the chiller condenser, a part of the cooling water (Q1) that dissipates heat through the cooling equipment is mixed with the remaining cooling water (Q2) that does not dissipate heat through the cooling equipment, and the cooling after the mixing Part of the water (Q3) enters the heat exchanger to exchange heat with the chilled water in the chilled water side loop, and after ...

The invention provides a system for testing a water chilling unit with a load. The system comprises a cooling device, a refrigerating device, a water chilling unit to be tested and a heat exchanger used for water and water heat exchange. Part of cooling water, cooled by the cooling device, in cooling water flowing out of a condenser of the water chilling unit and the rest of cooling water which is not cooled by the cooling device are mixed, part of the mixed cooling water enters the heat exchanger to conduct heat exchange with refrigerating water of a refrigerating water side loop, emits heat to the refrigerating water, then is mixed with the rest of the mixed cooling water and enters the condenser of the water chilling unit to absorb heat , and thus a cooling water side loop is formed. The refrigerating water flowing out of an evaporator of the water chilling unit passes through the refrigerating device, then enters the heat exchanger to conduct heat exchange with the cooling water of the cooling water side loop, absorbs heat from the cooling water and then enters the evaporator of the water chilling unit to emit heat, and thus the refrigerating water side loop is formed. The invention further provides a corresponding method. By the implementation of the system and the method, the water chilling unit can be tested under an unloaded condition.
Description
technical field [0001] The invention relates to the field of computer networks, and more specifically, to a system and method for on-load testing of chillers. Background technique [0002] With the rising cost of energy and people's emphasis on green environmental protection, the demand for energy saving in data centers is becoming stronger and stronger. On the premise of ensuring the safe and high-performance operation of IT equipment in the data center computer room, improving the energy utilization efficiency of the data center, energy saving and emission reduction has become one of the goals pursued by the data center infrastructure. [0003] The load capacity test of chillers used in existing data centers is in the form of erecting a dummy load at the end, that is, the dummy load provides the chiller load on the freezing side, and the cooling side is cooled by the cooling tower and sent to the condenser for circulation. In such a situation, it is necessary to spend a l...
