Embodiment 1

[0045] Such as Figure 1-7 As shown, the computer room air conditioner provided by Embodiment 1 of the present invention includes a cabinet assembly 1 and a heat exchanger 2 disposed in the cabinet assembly 1. The cabinet assembly 1 has positive air inlets located on different sides of the heat exchanger 2. The grille 101 and the lateral air intake grille 102, the vertical distance between the top of the lateral air intake grille 102 and the bottom of the cabinet assembly 1 H1=h1+a*h2, where h1 is the heat exchanger 2 The vertical distance between the bottom of and the bottom of the cabinet assembly 1, h2 is the height of the heat exchanger 2, 0<a<1.

[0046]Specifically, a can be defined as the lateral heat transfer coefficient of the computer room air conditioner, which can be used as a correction coefficient. The forward air intake grille 101 is located on the front of the cabinet assembly 1, and the front of the cabinet assembly 1, that is, the cabinet assembly 1 is place...

Embodiment 2

[0070] The main difference between the computer room air conditioner provided by this embodiment and the first embodiment is that the cabinet assembly 1 is set in a different way, which is specifically reflected in: refer to Figure 1-7As shown, in Embodiment 1, the cabinet assembly 1 includes a control cabinet 11 and at least one heat exchange cabinet 12, the control cabinet 11 and each heat exchange cabinet 12 are arranged side by side, and the control cabinet 11 is provided with an electric control box 4. Each heat exchange cabinet 12 is equipped with a heat exchanger 2, and the front of each heat exchange cabinet 12 is provided with a forward air intake grille 101, and each heat exchange cabinet 12 is connected to the control cabinet The non-contact sides of the body 11 are all provided with side air intake grilles 102; Figure 8-10 As shown, in this embodiment, the cabinet assembly 1 includes a heat exchange cabinet 12, the heat exchange cabinet 12 is provided with an ele...

Embodiment 3

[0076] The main difference between the computer room air conditioner provided in this embodiment and Embodiment 1 and Embodiment 2 is that the arrangement of the cabinet assembly 1 is different, which is specifically reflected in: refer to Figure 11-13 As shown, in this embodiment, the cabinet assembly 1 includes at least two heat exchange cabinets 12 arranged side by side, each heat exchange cabinet 12 is provided with a heat exchanger 2, and each heat exchange cabinet 12 has a A forward air intake grill 101 and a lateral air intake grill 102 are provided, and at least one heat exchange cabinet 12 is also provided with an electric control box 4 . Specifically, in this embodiment, at least two heat exchangers 2 are provided, and one electric control box 4 is provided, and one heat exchanger 2 and the electric control box 4 are installed in the same cabinet. Compared with Embodiment 1, the computer room air conditioner provided by this embodiment is more compact in structure, ...

Abstract

The invention is applicable to the technical field of air-conditioning and discloses an air conditioner in a machine room. The air conditioner comprises a cabinet assembly and a heat exchanger arranged in the cabinet assembly, wherein the cabinet assembly is provided with a forward air-inlet grille and a side air-inlet grille positioned on different sides of the heat exchanger; the vertical distance H1 between the top of the side air-inlet grille and the bottom of the cabinet assembly is equal to h1 plus a*h2, wherein h1 is the vertical distance between the bottom of the heat exchanger and the bottom of the cabinet assembly; h2 is height of the heat exchanger; and a is greater than 0 and less than 1. According to the height of the heat exchanger and the installation position of the heat exchanger in the cabinet assembly, optimization design is carried out on the air-inlet grille, so that on the premise that the cost and the complexity of the air conditioner are not increased, the heat exchanging effect of the air conditioner is effectively optimized, and the phenomena of air bias and insufficient heat exchange are reduced to further improve the cooling and energy-saving effects of equipment in the machine room to a greater degree, and the overall cost of the air conditioner and energy waste in the machine room are effectively reduced finally.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to machine room air conditioners. Background technique [0002] Computer room air conditioners generally include up-supply and down-supply fans. In the general up-supply fan type, there are usually air intake grilles on the front and side of the cabinet assembly, and the hot air with a higher temperature in the computer room passes through. The air intake grille enters the interior of the cabinet assembly, and after heat exchange through the evaporator, cold air with a lower temperature is formed and discharged into the machine room, so as to achieve the purpose of cooling the equipment in the machine room. [0003] However, when designing the intake grilles of computer room air conditioners in the prior art, there is no detailed research and design on the intake grilles of computer room air conditioners, so that the area of ​​the intake grills of existing computer room air...
