Abstract

The invention discloses a jet type heat exchanger unit with a two-stage-belt heat regenerator, which belongs to the technical field of energy utilization. The jet type heat exchanger unit is composed of a jet type heat pump of a first-stage-belt heat regenerator, a jet type heat pump of a second-stage-belt heat regenerator, a water-water heat exchanger, a secondary collateral circulation water pump, a valve and a connecting pipeline. The connecting pipeline consists of a working medium system pipeline and a water system pipeline, wherein the water system pipeline is divided into a primary side pipeline and a secondary side pipeline, the primary side pipeline adopts a series connection mode, and the secondary side pipeline adopts a parallel connection mode or a mixed connection mode. The jet type heat exchanger unit contributes to improvement of heat delivery capacity of a primary heat supply network and enlargement of the heat supply radius of large heat sources, and further contributes to water return and waste heat recovery of heat sources by utilizing low temperature to improve heat utilization ratio and economical efficiency of the heat sources.

Description

technical field [0001] The invention belongs to the technical field of energy utilization, and in particular relates to a two-stage jet heat exchange unit with a regenerator. Background technique [0002] With the rapid development of northern urbanization, the demand for heating load in northern cities and towns has increased dramatically. Due to the limitation of environmental protection factors in urban areas, newly-built centralized heat sources are generally located in the suburbs far away from the urban area. higher cost. In addition, with the continuous increase of urban floor area ratio, the heating area of ​​buildings in the original heating pipe network area has increased sharply, and the demand for heating load has increased sharply, which has highlighted the gap between the demand for heating in winter and the insufficient heat supply capacity of the heating network. contradictions between. The supply / return water temperature of conventional central heating te...
