Detailed Implementation
[0022] This utility model embodiment provides a high-temperature steam heat pump device, such as... Figure 1-4As shown, the system includes a mounting base plate 101, an evaporator 102, and a gas compressor 109. The evaporator 102 is fixedly mounted on one side of the top of the mounting base plate 101. A generator 108 is fixedly mounted on the top of the mounting base plate 101 and on one side of the evaporator 102. The gas compressor 109 is fixedly mounted between the generator 108 and the evaporator 102. A constant temperature water tank 103 is fixedly mounted on one side of the top of the mounting base plate 101. A steam pipe 110 is connected between the constant temperature water tank 103 and the top of the generator 108. A steam valve 111 is fixedly mounted on the top of the steam pipe 110. The gas compressor 109 is directly connected to the generator 108 and the constant temperature water tank 103 by pipes.
[0023] It is worth noting that the temperature inside the constant temperature water tank 103 is set at 80 degrees Celsius, and the other end of the steam valve 111 is connected to the outlet of the user's steam pipe, and the steam outlet flow rate is adjusted through the steam valve 111.
[0024] It should be further explained that a temperature sensor is fixedly installed inside the constant temperature water tank 103, and the temperature inside the constant temperature water tank 103 is further maintained stable through the cooperation of the sensor and flow regulation.
[0025] Furthermore, a heat exchange plate 106 is fixedly installed on one end face of the mounting base plate 101 and on one side of the constant temperature water tank 103.
[0026] Furthermore, a water supply pipe 105 is connected to one side of the heat exchange plate 106.
[0027] It should be further noted that the water supply pipe 105 is connected to the normal temperature water supply pipe.
[0028] Furthermore, a water pump 107 is fixedly installed between the steam generator 108 and the heat exchange plate 106, and a pipe is provided connecting the lower side of the steam generator 108 and the lower side of the constant temperature water tank 103 to both sides of the water pump 107.
[0029] Furthermore, an adjusting pipe 113 is provided between the constant temperature water tank 103 and the heat exchange plate 106.
[0030] Furthermore, a flow regulating valve 104 is provided inside the regulating pipe 113.
[0031] It should be noted that the flow regulating valve 104 can regulate the flow rate through the regulating pipe 113.
[0032] Furthermore, a pipe is provided to connect the heat exchange plate 106 and the evaporator 102.
[0033] Furthermore, a throttling device 112 is connected inside the pipe between the heat exchange plate 106 and the evaporator 102.
[0034] When this solution is used, the airflow compressor 109, heat exchange plate 106, flow regulating valve 104 and vapor generator 108 are connected by pipes to form a closed system. The refrigerant continuously circulates within this closed system, undergoes physical state changes, and exchanges heat with the outside world, thereby achieving cooling and heating.
[0035] In the evaporator, the refrigerant absorbs heat from the object being cooled and vaporizes into steam. This steam is then drawn in and compressed by the airflow compressor 109 to form a high-temperature, high-pressure refrigerant gas. This high-temperature, high-pressure refrigerant gas releases heat to the cooling medium through the heat exchange plate 106, condensing into a high-pressure liquid. After being throttled and depressurized by the flow regulating valve 104, it returns to the evaporator 102 as a low-temperature, low-pressure liquid, completing a refrigeration cycle.
[0036] During steam generation, the refrigeration system heats the 80°C water flowing into the steam generator at a 130°C condensing temperature. Part of the generated steam is used by the user; the steam valve 111 is adjusted according to customer needs to meet those requirements. The remaining steam enters the constant-temperature water tank 103 and mixes with the makeup water there, producing constant-temperature high-temperature water that can then enter the evaporator 102. This high-temperature water then enters the steam generator for the next cycle, continuously generating high-temperature steam.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
