Embodiment approach 1

[0025] When using the multi-mode volumetric heat exchange system of the present invention to provide domestic hot water to the domestic hot water supply pipeline and provide heat exchange to the heating water supply circuit at the same time, the heat exchange process is as follows:

[0026] Operate the heat exchange treatment control unit of the volumetric heat exchanger to control the opening of the first electronic control on-off valve and the second electric control on-off valve, and the heat exchange treatment control unit of the volumetric heat exchanger The flow rate collected by the meter controls the flow of the electronically controlled flow control valve on the domestic cold water inlet pipe, so that the water inlet flow of the domestic cold water inlet pipe is consistent with the water outlet flow of the domestic hot water outlet pipe; at the same time, the water circulation of the heat source water supply is turned on Pumps and heating water pumps in heating water s...

Embodiment approach 2

[0029] When the multi-mode volumetric heat exchange system of the present invention is used to provide domestic hot water only to the domestic hot water supply pipeline, the heat exchange process is specifically as follows:

[0030]Operate the heat exchange treatment control unit of the volumetric heat exchanger to control the closing of the first electronic control on-off valve and the second electric control on-off valve, and the heat exchange treatment control unit of the volumetric heat exchanger according to the electronic flow rate on the domestic hot water outlet pipe The flow rate collected by the meter controls the flow of the electronically controlled flow control valve on the domestic cold water inlet pipe, so that the water inlet flow of the domestic cold water inlet pipe is consistent with the water outlet flow of the domestic hot water outlet pipe; at the same time, the water circulation of the heat source water supply is turned on Pump. Since then, under the act...

Embodiment approach 3

[0033] When the multi-mode volumetric heat exchange system of the present invention is used to provide heat exchange only to the heating water supply circuit, the heat exchange process is specifically as follows:

[0034] Operate the heat exchange treatment control unit of the volumetric heat exchanger to control the opening of the second electronically controlled on-off valve and the closing of the first electronically controlled on-off valve, and when the outlet water of the domestic hot water outlet pipe does not provide domestic hot water to the domestic hot water supply pipeline In the case of a positive displacement heat exchanger, the heat exchange processing control unit of the volumetric heat exchanger controls the electronically controlled flow control valve on the domestic cold water inlet pipe to stop according to the flow rate collected by the electronic flowmeter on the domestic hot water outlet pipe, so that the flow rate of the domestic cold water inlet pipe The...

Abstract

The invention provides a multi-mode positive displacement heat exchange system and a heat exchange processing method thereof. The multi-mode positive displacement heat exchange system integrates heating heat supply and domestic hot water heat supply, two sets of different heat exchange systems do not need to be designed independently, the heating heat supply and the domestic hot water heat supply can be provided simultaneously or respectively by switching multiple working modes through the heat exchange system, in this way, the overall structure of the heat exchange system for supplying the heating heat and domestic hot water can be simplified, the overall size can be reduced, and reduction of system hardware equipment cost and occupied land construction cost can be facilitated. Furthermore, in the working mode of simultaneously providing the domestic hot water and heating water, compared with an existing common heat exchange system, the multi-mode positive displacement heat exchange system and the heat exchange processing method thereof have higher overall energy efficiency, reduction of system energy consumption can be facilitated, and thus the multi-mode positive displacement heat exchange system and the multi-mode heat exchange processing method thereof have quite good popularization and application prospects.

Description

technical field [0001] The invention relates to the fields of air conditioning technology and heating technology, in particular to a multi-mode volumetric heat exchange system and a heat exchange treatment method thereof. Background technique [0002] Hot water boilers, solar collectors, etc., are common heat source water supply equipment for heating and domestic hot water. In the existing heat exchange system, according to the heat supply design specification, the temperature of the water supplied by the boiler as the heat source is usually around 95°C. Between 75°C and 85°C, which is higher than the water supply temperature range of 45°C to 60°C for domestic hot water, so two different heat exchange systems are generally required to supply heating and domestic hot water respectively; while heating at the end When the water supply of the equipment is low-temperature hot water, the water temperature in the heating water supply circuit is usually between 40°C and 50°C. Altho...
