Heat pipe air conditioning all-in-one machine with phase change energy storage and control method thereof

Abstract

The invention discloses a heat pipe air conditioning all-in-one machine with phase change energy storage and a control method thereof. The phase change energy storage, heat pipe heat exchange and steam compression refrigeration are fully integrated, a phase change energy storage module is used for storing a natural cold source at the lower environment temperature, the advantages of a heat exchanger and a steam compression refrigeration air conditioner are combined, and the machine can adapt to changes of the environment temperature at different times; by additionally arranging the phase changeenergy storage module, the residual cold capacity at night is stored and used for refrigeration at the time with high temperature in the daytime, frequency switching between heat exchange and compression refrigeration is avoided while energy is saved, working stability is ensured, the service life is prolonged, at the same time, electricity at night is stored as part of cold capacity through thepeak and valley electric charges at night, time and space limitation of utilization of the cold capacity are broken through, the utilization time of the natural cold source is prolonged, energy is saved effectively, and the operation cost is reduced.

Description

technical field [0001] The invention relates to the field of integrated air conditioners, in particular to an integrated heat pipe air conditioner with phase change energy storage and a control method thereof. Background technique [0002] With the rapid development of national communication technology, the distribution of outdoor communication sites is more dense, and there are more heating devices and higher heat flux density in the control cabinet. A large number of temperature control devices are required to cool them down and maintain the long-term safe and stable operation of communication equipment. During the operation of equipment, the energy consumption of base station air conditioners accounts for about 46% of the total energy consumption. Therefore, how to reduce the energy consumption of air conditioners has become an important issue. In order to make full use of the natural cold source of nature and reduce the energy consumption of the air conditioning system...

AI Technical Summary

Problems solved by technology

However, since the heat exchanger is a passive heat exchange, the temperature in the cabinet must be higher than the ambient temperature to transfer heat. When the ambient temperature is high, the temperature in the cabinet cannot be effectively controlled, and it is difficult to ensure the operating temperature required by the electronic equipment.

[0003] The existing heat pipe air-conditioning all-in-ones on the market only take full advantage of the outdoor cold source in winter in some areas, and cannot adapt to small changes in the cold source over time.

However, in many areas in northern my country, the temperature difference between day and night is very obvious, usually reaching 10-20°C. In this case, if the existing heat pipe air conditioner is directly used, the operating conditions need to be adjusted according to the frequent changes in temperature in a short period of time. , Switching back and forth between the heat exchanger and the compression refrigeration cycle will not only fail to achieve a good energy-saving effect, but may also cause problems such as shortened life due to too frequent switching

At the same time, a large amount of cooling capacity at night cannot be fully utilized
