Description

1. Technical field [0001] The invention relates to a heat exchange device, in particular to an intelligent frequency conversion energy-saving heat exchange device with indirect heat exchange with a heat medium and cycle pressurization. 2. Background technology [0002] With the continuous development of urban construction, central heat supply in towns or regions has become the main force of social heat supply, but the centralized heat exchange equipment in the prior art often only combines heat exchangers, circulating water The equipment is connected by pipelines, occupying a large area, and there is no electronic control system. When the equipment is running, professional operators need to monitor it in real time. , can not achieve intelligent and energy-saving operation of heat exchange equipment; in addition, in heat exchange equipment, circulating water pumps and supplementary water pumps start frequently, which greatly affects the service life of the equipment. 3. Con...
