Abstract

The invention discloses an adaptive phase-change condensing air-conditioning system and its realization method. The adaptive phase-change condensing air-conditioning system comprises a compressor (1), a condenser (2), a throttling device (6), and a gas-liquid separator (7) and evaporator (8); the system also includes an adaptive phase change unit (4), a first valve mechanism, a second valve mechanism, a bypass pipe, a pressure sensor and a controller; the first valve and the second valve They are all controlled by the controller; the pressure sensor is located at the suction pipe and discharge pipe of the compressor to detect the suction air pressure and exhaust air pressure of the compressor; the pressure sensor is connected to the controller; the inlet of the bypass pipe and the self- The inlet of the adaptive phase change unit is connected with the outlet of the condenser through the first valve mechanism; the outlet of the bypass pipe and the outlet of the adaptive phase change unit are connected with the inlet of the throttling device through the second valve mechanism. The self-adaptive phase-change condensing air-conditioning system and its implementation method are easy to implement and have high operational reliability.

Description

Technical field [0001] The invention belongs to the technical field of air conditioning engineering, and relates to an adaptive phase change condensation air conditioning system and an implementation method thereof. Background technique [0002] With the increasing development of the information network industry, energy consumption problems in the communications industry have gradually become prominent. At present, this industry has become the fifth largest energy-consuming industry in the world, with carbon dioxide emissions accounting for 2.5% of the world’s emissions; especially now that the communication and mobile system is upgraded from 3G to 4G, the global average network connection speed in the third quarter of 2014 was 4.5Mbps. Signal data transmission is more and faster. The total amount of global information doubles every two years. In 2011, the total amount of data transmission was 1.8 trillion GB. By 2020, this value will increase to 35 trillion GB. Creation and pro...

Problems solved by technology

[0003] At present, when the air-conditioning system commonly used in the computer room is outdoors at high temperature in summer or the condenser is dirty and blocked, the condensing capacity of the condenser decreases, resulting in an excessively high exhaust pressure of the compressor, which generates a high-pressure alarm signal and forces the operation to stop, resulting in a sharp drop in the temperature in the computer room. When the cooling load in the computer room is high, the cooling capacity cannot be effectively generated to cool the computer room, and in severe cases, the communication equipment will be down. In winter, the outdoor ambient temperature is low. When the refrigeration system is running, due to the excessive condensation of the condenser, the liquid refrigerant stays In the condenser, the suction pressure of the compressor is too low, thereby generating a low-pressure alarm signal to force the operation to stop, resulting in an increase in the temperature in the machine room

[0004] It can be seen that the currently commonly used vapor compression refrigeration method cannot meet the uninterrupted cooling demand in the computer room (and other occasions similar to the computer room, such as warehouses with high temperature control requirements) throughout the year. Therefore, it is necessary to design a An adaptive phase-change condensing air-conditioning system and its implementation method
