A heat recovery integrated box

Abstract

The invention discloses a heat energy recovering integrated box, which comprises a box body, a first heat exchanger, a second heat exchanger, a buffer expansion tank, a circulating water pump and a conveying water pump, wherein the first heat exchanger and the second heater changer are arranged on one side of a bottom plate of the box body in sequence; the buffer expansion tank, the circulating water pump and the conveying water pump are arranged in sequence on the other side of the bottom plate of the box body; the hot end inlet of the first heat exchanger is connected with a high-temperature cooling water pipeline; the hot end outlet of the first heat exchanger is connected with the inlet of the second heat exchanger through a pipeline; the cold end of the first heat exchanger is connected with the inlet and outlet of a low-temperature hot water pipeline through a pipeline; the cold end of the second heat exchanger is connected with the inlets and outlets of low-temperature hot water pipelines at different temperature segments; the side wall of the box body is provided with a high-temperature circulating water pipe interface and a low-temperature hot water pipe interface; a water inlet / outlet pipe is provided with a control valve. By adopting the heat energy recovering integrated box, high-order heat energy generated by a central air conditioning system or an aerodynamic system in a plant can be effectively recovered, and high integration degree and high flexibility are achieved.

Description

technical field [0001] The invention relates to a heat energy recovery integration box. Background technique [0002] In industrial production, energy saving is an important measure to reduce costs. In the existing air conditioning system, chillers, air compressors and other equipment will generate a large amount of high-order heat energy when they compress the outlet of the main body during operation. After these high-order heat energy is absorbed into hot water by the cooling water in the cooler of the equipment itself, it is generally The tower dissipates heat from the condenser or cooler and then recycles it. This part of the heat is not only wasted, but also consumes additional paid electric energy to obtain high-order heat energy in the production activities of the factory, which becomes a large production cost for the factory. current situation.

Problems solved by technology

In the existing air conditioning system, chillers, air compressors and other equipment will generate a large amount of high-order heat energy when they compress the outlet of the main body during operation. After these high-order heat energy is absorbed into hot water by the cooling water in the cooler of the equipment itself, it is generally The tower dissipates heat from the condenser or cooler and then recycles it. This part of the heat is not only wasted, but also consumes additional paid electric energy to obtain high-order heat energy in the production activities of the factory, which becomes a large production cost for the factory. current situation

Some existing heat recovery systems have a fixed capacity set for the evaluation data of the power system at a fixed moment in the factory, and cannot automatically adjust on demand according to the supply load changes of the power system equipment, resulting in the final required high-order energy recovery rate insufficient
