Embodiment Construction

[0032] The present invention will be described below in conjunction with the accompanying drawings.

[0033] figure 1 It is a schematic diagram of the optimal structure of the return air precooling heat exchange system of a large air-conditioning refrigerator. The system includes an indoor heat exchanger 2, a fluid circuit 3, an outdoor heat exchanger 4, and an outdoor cooling device 5 connected in sequence. The indoor heat exchanger 2 It is installed at the air return port 6 of the indoor unit of the large-scale air-conditioning refrigerator 1, and the indoor heat exchanger 2 is provided with an integral air outlet 18 facing the air return port 6. The integral air outlet 18 matches the air return port 6, and the indoor heat exchanger 2 The size also matches with this return air outlet 6. The indoor heat exchanger 2 includes one or more connected metal flat tube heat exchangers, which may include single or multiple metal flat tubes and Aluminum fins connected or welded betwe...

Abstract

The invention relates to a return air precooling heat transfer system of a large air conditioning refrigerator, which comprises an indoor heat exchanger, a fluid loop, an outdoor heat exchanger and an outer door heat sink connected in sequence, wherein the indoor heat exchanger is arranged in the return air port of the indoor set of the large air conditioning refrigerator, and comprises one or a plurality of connected metal flat tubular exchangers arranged to ensure that the indoor exchanger is provided with an integral air outlet towards the return air port; the integral air outlet is matched with the return air port; and the return air of the large air conditioning refrigerator penetrates through the metal flat tubular exchangers, is cooled by the metal flat tubular exchangers through heat exchange, and then enters the return air port through the integral air outlet. The invention is highly effective and compact, has high efficiency and saves energy by precooling the return air.

Description

technical field [0001] The invention relates to a heat exchange technology, in particular to a return air precooling heat exchange system of a large air conditioner refrigerator. Background technique [0002] Large-scale communication equipment rooms or server equipment rooms usually use multiple large-scale air-conditioning refrigerators to run throughout the year to cool the indoor air in the equipment room due to the large amount of heat that needs to be dissipated, which consumes a large amount of electricity every year. Moreover, in winter or in areas where the outside air temperature is low, the outdoor cold energy cannot be effectively utilized, which is actually a great waste of energy. [0003] Traditional air reheating or pre-cooling systems are bulky and have low heat exchange efficiency, making it difficult to apply heat dissipation in computer rooms with limited space. Contents of the invention [0004] The present invention aims at the problem that the exist...
