Temperature/pressure-change heating heat exchanger unit

Abstract

The invention discloses a temperature/pressure-change heating heat exchanger unit. The temperature/pressure-change heating heat exchanger unit mainly consists of a temperature control valve, a plate heat exchanger, an expansion water tank, a water replenishment pump, a flow detecting device, a circulating pump, an outdoor temperature sensor and a control cabinet, wherein a primary side of the plate heat exchanger is respectively connected with a primary water supply pipe and a primary water return pipe; inlet water of a secondary side of the plate heat exchanger is connected by a secondary water return pipe after passing through the circulating pump; a heat metering device is arranged on a primary water supply pipe; the flow detecting device is mounted on a secondary water return pipe; a frequency converter 1, a frequency converter 2 and a touch screen are integrated and mounted in the control cabinet; and a remote communication interface is additionally arranged in the control cabinet. The temperature/pressure-change heating heat exchanger unit has the beneficial effects of possession of temperature/pressure-change heating energy saving comfortable effect, complete system configurations, perfect protection function, simple and direct operation, good heat supply use effect, high intelligent degree and achievement of unattended operation.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a variable temperature and variable pressure heating heat exchange unit. Background technique [0002] With the rapid development of urbanization, central heating is becoming more and more popular. Heat exchange units have the advantages of energy saving, capital saving, and environmental protection, and are the main force of central heating at present. However, most of the heat exchange units in the prior art are relatively simple to control, and the degree of intelligence is not high, and they are not well suited to the energy-saving, comfort, and variable temperature and pressure requirements of the user's on-demand heating. The outlet water pressure is always a constant set value, no matter how big the indoor and outdoor temperature difference is, or how the heating flow changes, the heating outlet water temperature and outlet water pressure are maintained at a constant...

Problems solved by technology

However, most of the heat exchange units in the prior art are relatively simple to control, and the degree of intelligence is not high, and they are not well suited to the energy-saving, comfort, and variable temperature and pressure requirements of the user's on-demand heating. The outlet water pressure is always a constant set value. No matter how big the indoor and outdoor temperature difference is, how the heating flow changes, the heating outlet water temperature and outlet water pressure are maintained at a constant set value, and there are problems such as heat energy, electric energy waste and poor comfort.
