Multi-housing-section, copper-pipe-water-channel and single-separating-plate type cold water heat exchanger

Abstract

A multi-housing-section, copper-pipe-water-channel and single-separating-plate type cold water heat exchanger comprises housings, a front end cover, a front separating plate, a separating plate, a rear end cover, a rear separating plate and a copper pipe, wherein the housings are cylindrical cast iron housings; a plurality of housings are connected in series in an end-to-end manner and are sealed;each housing is treated as the housing of an evaporator of a refrigerating system, and each housing is provided with a refrigerant inlet, a refrigerant outlet, an air exhausting port and an air outlet; a bottom housing of the front end cover is 8-shaped; two ends of the separating plate are correspondingly welded to the end parts of two housings; a water chamber is formed between the rear end cover and the rear separating plate; an annular groove is formed in the rear separating plate. According to the multi-sectional-housing, copper-pipe-water-channel and single-separating-plate type cold water heat exchanger, water channels of the evaporators of a plurality of refrigerating systems are shared, so that the occupied space is reduced; and the stable working condition is ensured for operation based on the actual operation condition.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning, in particular to a cold water heat exchanger with a multi-section shell copper pipe waterway and a single partition plate. Background technique [0002] Both the evaporator and condenser in the refrigeration system are a specific form of heat exchanger. In the central air-conditioning industry, the evaporator has a variety of forms, including shell-and-tube, plate and other forms. The shell-and-tube type is generally suitable for air-cooled units that prepare cold water. In most regions of the country, different seasonal differences lead to different cooling capacity. For example, during the peak cooling time in summer, full power is required for cooling, but in winter and other seasons when cooling demand is low, full power is not required. At present, there is also frequency conversion technology that can solve the problem of cooling capacity changes within a certain range, bu...

Problems solved by technology

However, the arrangement of multiple refrigeration systems will lead to the problem of space utilization. Generally, the condenser can be installed outdoors, but as an evaporator, it must be installed indoors, and the space for the evaporator is limited. Multiple refrigeration systems must be considered. The installation space of the evaporator of the system
