Abstract

The invention discloses a high-efficiency jetting type heat exchange machine set, belonging to the technical field of energy source utilization. The high-efficiency jetting type heat exchange machine set consists of a high-efficiency jetting type heat pump, a water-water heat exchanger, a circulating water pump, a connection pipe, a valve and other accessories, wherein the high-efficiency jetting type heat pump is of a two-stage condensation and two-stage evaporation structure or a two-stage condensation and one-stage evaporation structure, and the connection pipe is divided into a working medium system pipe and a water system pipe, wherein the water system pipe is divided into primary side pipes and secondary side pipes, the primary side pipes are connected in series, and the secondary side pipes are connected in parallel and series. Depending on the jetting type heat pump technique, the high-efficiency jetting type heat exchange machine set disclosed by the invention can perform cascade utilization to the water supply heat of the primary side pipes through certain pipe connection manners, therefore, returned water temperature of the primary side pipes is greatly reduced, so that the returned water supply temperature difference of the primary side pipes is increased, and heat transfer capability of hot water of the primary side pipes and the secondary side pipes is greatly improved.

Description

Technical field [0001] The invention belongs to the technical field of energy utilization, and specifically relates to a high-efficiency jet heat exchange unit. Background technique [0002] With the continuous increase in the scale of urban central heating and the increase in urban plot ratio, the demand for heating load in northern cities and towns has increased sharply. Due to environmental protection factors, newly-built central heating sources are generally located in the suburbs far away from the heat load center. Hot water needs to be transported over long distances, which results in higher energy consumption for pipe network transmission, higher pipe network investment, and higher central heating costs. In addition, with the continuous increase of the urban floor area ratio, the heating area of ​​buildings in the original heating pipe network area has increased sharply, and the heating load demand has increased sharply. This has highlighted the lack of winter heating dema...
