An energy-saving air conditioner

Abstract

The invention discloses an energy-saving air conditioner, which relates to the technical field of air conditioning and refrigeration, and includes a refrigeration system, a ventilation system and a control system. The refrigeration system includes an air-cooled circulation system and a water-cooled circulation system. The first cold water plate heat exchanger; the water cooling circulation system includes a cooling tower, a wet bulb thermometer and a cooling pipe are arranged on the side wall of the cooling tower, a circulating water tank is arranged at the bottom of the cooling tower, and a spray head is arranged in the cooling tower, and the spray head passes through The pipeline is arranged in communication with the circulating water tank, and a water pumping device is also arranged on one side of the cooling tower; the ventilation system includes an air conditioner inner unit and a second cold water plate heat exchanger. The invention provides an energy-saving air conditioner with diversified refrigeration modes, low energy consumption for refrigeration, few compressor usage times and long air conditioner life.

Description

technical field [0001] The invention relates to the technical field of air conditioning and refrigeration, in particular to an energy-saving air conditioner. Background technique [0002] Under the external environment of the global energy crisis and increasingly serious environmental problems, and the internal environment of my country's tight power supply, energy saving is of great significance to my country's economic development and modernization. Designing energy-saving air-conditioning products can actively respond to the country's needs energy saving policy. [0003] At present, the number of large and medium-sized subway equipment rooms is increasing, and the load is also increasing in application scenarios (such as large computer rooms, etc.), reducing the cooling power consumption of the air-conditioning system in the equipment room, and reducing the pPUE value. Most of the air conditioners used in cooling equipment rooms throughout the year are air-cooled air cond...

AI Technical Summary

Problems solved by technology

Most of the air conditioners used in cooling equipment rooms throughout the year are air-cooled air conditioners; they are all single vapor compression refrigeration units, and the transfer of heat depends entirely on a single compression refrigeration cycle. In many high-latitude areas, it is often outdoors The temperature is lower than the indoor temperature, and the heat spontaneously diffuses and transfers to the outside with the temperature gradient. Using the air conditioner inverter compressor refrigeration cycle to transfer heat is a great waste of energy

In addition, frequent start and stop of the frequency conversion compressor will increase the loss of the compression equipment, shorten its service life, and eventually lead to early damage to the entire air conditioning system, so there is room for improvement
