Intelligent heat-exchange machine set

Abstract

The invention provides an intelligent heat-exchange machine set, which comprises a steam inlet, a heat exchanger, a water-circulating pump, a water-replenishing pump, a water-replenishing box, a backwater port, a water-supply port and a condensed-water outlet, wherein the steam inlet is connected with the heat exchanger through an electric regulating valve; an exhaust pipe and a drain valve are arranged on the heat exchanger; one end of the circulating pump is connected with the heat exchanger, and the other end of the circulating pump is connected with a backwater pipe; two ends of the backwater pipe are connected with the water-replenishing pump and the backwater port respectively; and the input ends of the electric regulating valve and the water-replenishing pump are connected with the output end of a control circuit board. The machine set has the advantages that: 1, the machine set can perform unattended automatic operation, automatic water replenishing and automatic alarming through the control technology of the control circuit board; 2, the machine set is simple in structure and good in safety performance; 3, the machine set is small in volume and low in manufacturing cost; and 4, the machine set can realize constant-temperature heat supply.

Description

Technical field: [0001] The invention belongs to a heat exchange unit, in particular to an intelligent heat exchange unit capable of automatic operation. Background technique: [0002] The heat exchange unit is a device that provides the heat (cold capacity) required by the heat (cold) loads of heating, ventilation, air conditioning, production and living in various buildings. The heat exchange unit is mainly composed of a heat exchanger, a circulating water pump, and a make-up water pump. These heat exchange units often only connect heat exchangers, circulating water pumps, and make-up water pumps with pipelines. There is no electronic control system. When the equipment is running, professional operators need to monitor it from time to time, and it occupies a large area and the control is complicated. In recent years, many heat exchange units have adopted automatic control technology, which initially solved the problem of manual operation, but the configuration of the elec...

Problems solved by technology

These heat exchange units often only connect heat exchangers, circulating water pumps, make-up water pumps, etc. with pipelines, without an electronic control system. When the equipment is running, professional operators need to monitor it from time to time, and it occupies a large area and is complicated to control.

In recent years, many heat exchange units have adopted automatic control technology, which initially solved the problem of manual operation, but the configuration of the electronic control system is unreasonable, and the optimal control of heat exchange units cannot be achieved.
