Embodiment 1

[0037] refer to figure 1 , is a high and low temperature all-in-one machine disclosed by the present invention, comprising a box body 1, which is provided with a medium inlet pipe 2, a medium outlet pipe 3, a compressor 4 for refrigeration, and a heating device 40 for heating , The box body 1 is also provided with a medium box 5 for storing medium, and the medium in this embodiment is heat transfer oil. The compressor 4 is connected with an inner heat exchanger 41 for heat exchange and an outer heat exchanger 42 for heat exchange. The heating device 40 of this embodiment includes a heating box, an electric heating tube arranged in the heating box, and a medium outlet pipe 3 through the heating box. One end of the medium inlet pipe 2 and the medium outlet pipe 3 is located inside the box body 1, and the other end passes out of the box body 1 for communication with subsequent equipment for use of the medium.

[0038]The end of the medium inlet pipe 2 located in the box body 1 ...

Embodiment 2

[0049] A high and low temperature all-in-one machine, the difference between Embodiment 2 and Embodiment 1 is:

[0050] refer to figure 1 and image 3 The exhaust valve 8 is a ball valve. The exhaust valve 8 includes a valve seat 81, a spherical valve core 82, and a handle 83 located outside the valve seat 81. The handle 83 is used to drive the valve core 82 to rotate. Through the communicating port 821. The valve seat 81 is a straight-through type, the valve seat 81 is fixed on the middle section 72, and the connecting line between the inlet and outlet ends of the valve seat 81 is along the vertical direction.

[0051] The middle section 72 includes a detachable installation section 73 . The installation section 73 is located below the exhaust valve 8 and close to the valve seat 81 . The installation section 73 connects the middle section 72 . The installation section 73 is cylindrical, the two ends of the installation section 73 are screwed to the middle section 72, and t...

Abstract

The invention discloses a high and low temperature all-in-one machine, which relates to a heat exchange device. The main points of the technical solution are: including a box body, a medium inlet pipe, a medium outlet pipe, a compressor for refrigeration, and a heating device for heating , the compressor and the heating device are connected with an internal heat exchanger for heat exchange, the medium inlet pipe and the medium outlet pipe are respectively connected to the inlet and outlet ends of the internal heat exchanger, and also include a medium box and an exhaust pipe. The top of the medium box is connected with a The medium adding pipe, the medium outlet pipe is located below the medium inlet pipe, one end of the exhaust pipe is connected to the inner top of the medium outlet pipe, and the other end of the exhaust pipe is connected to the inner top of the medium inlet pipe or the media box; the exhaust pipe is provided with Control its on-off exhaust valve. Even if the closing of the exhaust valve is delayed, the medium in the high and low temperature integrated machine will not be discharged from the circulation system to cause safety hazards; by setting the floating plate, the medium in the exhaust pipe will not enter the medium inlet pipe, preventing the interaction of hot and cold media run away.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a high and low temperature integrated machine. Background technique [0002] The high and low temperature all-in-one machine is a heat exchange device that integrates two functions of cooling and heating. Its working principle is similar to that of an air conditioner, but the range of cooling and heating is much larger than that of an air conditioner. The high and low temperature all-in-one machine is suitable for equipment connected to reaction kettles for refrigeration and heating reactions in the pharmaceutical, chemical, and laboratory industries. Commonly used refrigerants for high and low temperature integrated machines include circulating water, water at 7-20°C, salt water below 0°C, refrigerants below -40°C, etc. Commonly used heat media include hot water, heat transfer oil, etc. Refrigerants and heat media can be collectively referred to as media. [0003] The Chinese utility ...
