Description

Technical Field

[0001] The present application relates to the technical field of air-to-water systems, and in particular to a water system radiant cooling water mixing component. Background Art

[0002] Air conditioners and air source heat pump units have been widely used. In view of the dual cooling and heating functions of the main unit, the existing installation method is: relying solely on fan discs for cooling and floor heating plus fan discs for heating. However, with the development of intelligent control technology and frequency conversion technology, a more comfortable and energy-saving operating mode has emerged, that is, the combination of fan discs and floor heating for cooling in summer: the fan discs blow cold air to achieve the effects of heat exchange and dehumidification, and the supercooled water from the floor heating is used for radiant cooling. The two cooling methods are superimposed to achieve the purpose of less wind feeling and more comfortable temperature and humidity.

[0003] In the existing technology, most mixed water pump stations cannot achieve full frequency conversion operation, which leads to energy waste. For this reason, we propose a water system radiation cooling mixed water component to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art that most water mixing pump stations cannot achieve full frequency conversion operation, thereby causing energy waste, and to propose a water system radiation cooling water mixing component.

[0005] The present application provides a water system radiant cooling water mixing component that adopts the following technical solution:

[0006] A water system radiant cooling water mixing component, comprising:

[0007] Air energy unit;

[0008] A first connecting pipe and a second connecting pipe, one end of each of the first connecting pipe and the second connecting pipe being connected to the air energy unit;

[0009] Intelligent electronic control, intelligent electronic control is connected with indoor control panel;

[0010] A buffer water tank, the outer side of which is connected to a thermal insulation layer, the other ends of the first connecting pipe and the second connecting pipe are both connected to the buffer water tank, and the top and bottom of the buffer water tank are respectively provided with an automatic exhaust valve and a sewage valve;

[0011] An expansion tank is connected to a buffer water tank, and the buffer water tank is connected to a third connecting pipe, a fourth connecting pipe, a fifth connecting pipe and a sixth connecting pipe.

[0012] Furthermore, a fan disk is connected between the third connecting pipe and the fourth connecting pipe, and a fan disk circulation pump is connected to the third connecting pipe.

[0013] Furthermore, a seventh connecting pipe is connected between the fifth connecting pipe and the sixth connecting pipe, and the seventh connecting pipe is connected to a water mixing pump and a second electric valve.

[0014] Furthermore, the fifth connecting pipe is connected to the first electric valve and the third temperature sensor, and the sixth connecting pipe is connected to the second temperature sensor.

[0015] Furthermore, the buffer water tank is connected to a first temperature sensor, and the fourth connecting pipe is connected to a fourth temperature sensor.

[0016] Furthermore, floor heating is connected between the fifth connecting pipe and the sixth connecting pipe, and a floor heating circulation pump is connected to the fifth connecting pipe.

[0017] Furthermore, the second connecting pipe is connected to an air circulation pump, and the second connecting pipe is connected to a filter.

[0018] In summary, this application has the following beneficial technical effects:

[0019] This solution opens the mixing pump and the second electric valve to allow water or antifreeze to circulate in the floor heating pipes. At this time, no cold water or antifreeze participates in the circulation, and the temperatures of the second temperature sensor and the third temperature sensor are equal. After the mixing pump is opened, the first electric valve and the floor heating circulation pump are opened with a delay, and the floor heating circulation pump starts to run at a certain speed. At this time, the cold water or antifreeze in the buffer water tank is mixed with the original water of the floor heating and cooled. When the third temperature sensor reaches the set temperature calculated by the system (above the dew point temperature), the frequency conversion pump maintains the speed. When the indoor temperature and humidity change, the speed of the floor heating circulation pump will also change, so that the third temperature sensor will always change with the set value. In this process, the intelligent electronic control will collect the overall operating status of the system and control the other three pumps to operate at a variable frequency, so that the system is always in a state of precise temperature control and high efficiency and energy saving.

[0020] During use, the utility model can collect the overall operating status of the system through intelligent electronic control and control the other three pumps to perform variable frequency operation, thereby achieving the goals of precise temperature control and efficient energy saving.

[0032] The implementation principle of a water system radiation cooling mixing water component of the embodiment of the present application is: when in use, when cooling in summer, the air energy circulation pump 9 is connected to the water inlet of the air energy unit 1, and the water or antifreeze in the system is cooled by the air energy unit 1 through the first connecting pipe 2 to the buffer water tank 4 through the operation of the air energy circulation pump 9.

In this process, the intelligent electronic control 11 will collect the overall operating status of the system and control the other three pumps to perform variable frequency operation, so that the system is always in a state of precise temperature control and high efficiency energy saving.
