Embodiment Construction

[0013] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0014] A single-system dry evaporator for a chiller, including a casing 1, copper pipes 2, front end cover 3, rear end cover 4, and spoiler 5; the casing 1 is a cylindrical shell, which is provided with a water inlet 11 and a water outlet 12 , vent hole 13 and drain hole 14; Described water inlet 11 is connected to water inlet pipe by thread, and described water outlet 12 is connected to water outlet pipe by thread, and described vent hole 13 is threadedly connected with sleeve pipe, and this sleeve pipe is connected again An exhaust valve is installed; the drain hole 14 is threadedly connected with a sleeve, and the sleeve is installed with an exhaust valve; the shell 1 occupies all the space of the entire evaporator, so the water inlet and outlet of the medium can be preset on the shell 1. Save a ...

Abstract

A water chilling unit single-system dry type evaporator comprises a shell, a copper tube, a front end cover, a rear end cover and spoilers. A front bottom plate and a rear bottom plate are welded to the two ends of the shell correspondingly, and the front bottom plate is a round plate and is welded to the front end of the shell. The inner wall face and the outer wall face of the copper tube are surfaces with threads. Sleeves are welded to a medium inlet and a medium outlet. The rear end cover is welded to the rear end of the shell, and the rear end cover is formed by welding a cylindrical shell and part of a spherical face. A plurality of fixed rods are arranged in the manner of penetrating each spoiler. The shells are thin shells, components at the front end and the rear end are mounted through bolts or flanges, therefore, after the front bottom plate and the rear bottom plate are welded, bolt holes or flange holes can be formed in the front bottom plate and the rear bottom plate, andother components can be mounted conveniently.

Description

technical field [0001] The invention relates to the technical field of central air conditioning, in particular to a single-system dry evaporator of a chiller. Background technique [0002] The central air conditioner uses the form of centralized cooling to provide cold water for the entire building, and then transmits the cold energy to each room step by step through heat exchange components such as fan coil units. Although the building structure generally reserves a certain space for the central air-conditioning unit, the evaporator of the central air-conditioning chiller has a variety of forms, including shell-and-tube heat exchangers, plate heat exchangers and other structures, which need to occupy a large area. Space. Especially when the demand for cooling capacity is particularly huge, when multiple chillers are required to work at the same time to meet the cooling capacity requirements, it is necessary to arrange as many evaporators as possible in the same space.
