[0032] The heating machine is a device for raising indoor temperature, which mainly transmits heat energy to indoor radiators through heat exchange process to achieve the purpose of heating. The main components of the heating machine include heat source, heat exchanger and control system. The heat source can be gas, electricity or solar energy and other forms, the heat exchanger is responsible for transmitting heat energy from the heat source to the medium, and the control system intelligently adjusts the whole process to ensure the stability of indoor temperature and energy saving effect. The main function of the heating machine is to raise indoor temperature and provide comfortable indoor environment. Through the heat exchange process, the heating machine can transmit heat energy to the indoor radiator to raise the indoor temperature and meet the heating needs of people. However, most of the current heating machines cannot flexibly adjust the heat exchange efficiency according to the indoor temperature, cannot reasonably utilize heat, and consume a lot of energy.

[0033] Based on this, please refer to Figure 1 and Figure 2 The heating machine system 100 provided in the embodiment of the utility model can effectively improve the technical problems mentioned above. The heating machine system 100 can control the heat exchange efficiency of the heat exchanger 140 according to the actual situation, and play the role of energy saving and environmental protection. The heating machine system 100 is applied to the heating machine 1000 or the air conditioner, and the equipment with the heating machine system 100 has the same functions as described above, which will not be repeated here.

[0034] Figure 1 For the schematic view of the heating machine 1000 provided in the embodiment of the utility model, please refer to Figure 1 The heating machine 1000 in the embodiment includes a shell 200 and a heating machine system 100, and the heating machine system 100 is arranged in the shell 200. By arranging the heating machine system 100 in the shell 200, the protection of the heating machine system 100 can be realized, and by embedding the compressor 120, the maintenance and installation will be more convenient and fast. In addition to the heating machine system 100, the heating machine 1000 can also include an exhaust system, a safety protection system and other structures to realize various functions of the heating machine 1000 according to actual use requirements, which will not be limited here. The exhaust system is used to discharge the exhaust gas generated in the combustion process to the outdoor to ensure the freshness and safety of indoor air. The safety protection system can include one or more of the overheating protection system, the inclination protection system and the circuit protection system. The overheating protection system can automatically cut off the power when the temperature is too high to prevent equipment damage or fire. The inclination protection system is used to automatically shut down the equipment to prevent fire in case of accidental inclination of the heating machine 1000. The circuit protection system is used to prevent electrical faults.

[0035] In addition, the shell 200 in the embodiment is provided with an air inlet 210 and an air outlet 220, and the air inlet 210 and the air outlet 220 are arranged above the shell 200. That is, the heating machine 1000 in the embodiment adopts an up-in and up-out design. Hot air is lighter than cold air, so it will naturally rise upward. By adopting the up-in and up-out design, the hot air will directly flow to the upper part of the room after being discharged through the upper part, which helps the natural convection circulation of the air and makes the temperature of the whole room evenly distributed. In addition, the up-in and up-out design can also avoid the concentration of heat near the heating machine 1000. In addition, the up-in and up-out design can also make the hot air better distributed in the whole room, thereby reducing the waste of heat; in this way, the heating machine 1000 does not need to run for a long time to reach the set temperature, which helps to improve the energy utilization efficiency and save energy. Of course, the air inlet 210 and the air outlet 220 can also be arranged at other positions of the shell 200, which is not limited herein.

[0036] In order to reduce the emission pollution of the heating machine 1000, the refrigerant used by the heating machine 1000 in the embodiment is R290 (propane) refrigerant. The R290 refrigerant has the characteristics of high efficiency and environmental protection, and compared with the traditional refrigerant, it can effectively reduce the emission pollution and will not cause any damage to the ozone layer, which is very environmentally friendly. The R290 refrigerant can provide effective refrigeration effect under low energy consumption, and has good heat conduction performance, so that the refrigeration efficiency is high and cold air can be quickly provided, and the energy efficiency ratio is high. That is, as a natural and environmentally friendly refrigerant, the R290 refrigerant has the advantages of low global warming potential and zero ozone layer consumption, high energy efficiency and low cost. Of course, the heating machine 1000 can also use other refrigerants according to the actual use environment and cost requirements, which is not limited herein.

[0037] The heating machine system 100 will be described in detail below.

The four-way valve 130 includes a first valve port 131, a second valve port 132, a third valve port 133, and a fourth valve port 134. The outlet of the compressor 120 is in communication with the first valve port 131, and the third valve port 133 is in communication with the inlet of the compressor 120. The outlet of the evaporator 110 is in communication with the second valve port 132, the fourth valve port 134 is in communication with the first inlet of the heat exchanger 140, and the first outlet of the heat exchanger 140 is in communication with the inlet of the evaporator 110.

By arranging the plurality of water outlet branch pipelines 1522 and controlling each water outlet branch pipeline 1522 through the control valve, the flow rate of the heat exchange medium in each water outlet branch pipeline 1522 can be controlled by adjusting the control valve, so that the heat exchange efficiency of the heat exchanger 140 can be controlled according to the actual situation, to realize rational utilization of heat and play a role in energy saving and environmental protection. The heat exchanger 140 is used to realize heat exchange between the external heat exchange medium and the internal system.

[0039] The heating machine system 100 can rapidly increase the indoor temperature in a short time, has higher heat efficiency compared with the traditional water heating, can save energy, and can also shorten the heating time. In addition, the heating machine system 100 can automatically adjust according to the indoor temperature and humidity, so that the indoor environment is more comfortable. The evaporator 110 in the embodiment is a fin evaporator 110, and the heating machine system 100 can effectively utilize energy and can more efficiently utilize energy. Compared with the traditional heating machine 1000, the fin heat exchanger can directly transfer heat to indoor air instead of heating indoor air through hot water, so that energy can be more efficiently utilized.

[0040] Specifically, the water outlet branch 1522 in the embodiment is two, and the control valve is a three-way valve. One valve port of the three-way valve is in communication with the water outlet main pipeline 1521, one valve port of the three-way valve is in communication with the first water outlet branch 1522, and one valve port of the three-way valve is in communication with the second water outlet branch 1522. By the opening and closing relationship between the three valve ports of the three-way valve and the opening degree of each valve port, the heat exchange medium flow from the water outlet main pipeline 1521 to each water outlet branch 1522 is controlled, so as to control the heat exchange efficiency of the heat exchanger 140. Of course, the water outlet branch 1522 can also be three, four, five or more, which is not limited here. The number of control valves can be one or more. When the number of control valves is more, a control valve can be arranged between each water outlet branch 1522 and the water outlet main pipeline 1521, that is, the number of water outlet branches 1522 and control valves is the same, and each control valve controls one water outlet branch 1522. Of course, the number of control valves can be less than the number of water outlet branches 1522, and one control valve can control multiple water outlet branches 1522, which is not limited here.

[0041] Please continue to refer to Figure 2 In order to control the working state of the heat exchanger 140, the heating machine system 100 in the embodiment further comprises a water flow switch 160, and the water flow switch 160 is arranged on the water inlet pipeline 151. According to the actual use requirement, the opening or closing of the water flow switch 160 is controlled, so as to control the working state of the heat exchanger 140.

[0042] In order to monitor the temperature of the heat exchange medium entering the heat exchanger 140, the heating machine system 100 in the embodiment further comprises a first temperature probe 171, and the first temperature probe 171 is arranged on the water inlet pipeline 151, and the water flow switch 160 is located between the second inlet of the heat exchanger 140 and the first temperature probe 171.

The heating machine system 100 can adjust the opening and closing of the water flow switch 160 and the control valve according to the temperature value feedback obtained by the first temperature probe 171 and the second temperature probe 172.

[0043] In addition, the heating machine system 100 in the embodiment further comprises a regulating valve 173, and the regulating valve 173 is arranged on the water outlet main pipeline 1521. The regulating valve 173 is arranged to balance the pressure of the heating machine system 100, so as to ensure the normal operation of the heating machine system 100. The regulating valve 173 can be one or more of an exhaust valve, a pressure relief valve or a micro bubble valve. The exhaust valve is mainly used to exhaust the gas in the pipeline system, so as to prevent the system pressure from being unbalanced due to the accumulation of gas. The working principle is that when the internal pressure of the pipeline exceeds the set value, the exhaust valve will automatically open to release the internal gas, so that the system pressure returns to balance; when the system pressure drops below the set value, the exhaust valve will be closed to prevent the gas from continuing to be discharged. The pressure relief valve is a kind of hydraulic control valve, which is mainly used to automatically release pressure when the pressure is too high, so as to protect the system and equipment; its working principle is to open or close the valve by controlling the pressure change in the chamber, so as to release the excessive pressure. The micro bubble valve is mainly used to exhaust the micro bubbles and impurities in the heating machine system 100.

[0044] Please refer to Figure 2 , the heating machine system 100 further comprises a first filter 174, a second filter 175 and an expansion valve 176, and the first filter 174, the expansion valve 176 and the second filter 175 are arranged in sequence between the inlet of the evaporator 110 and the first outlet of the heat exchanger 140.

The first filter 174 can filter the heat transfer agent entering from the evaporator 110 when the heating machine system 100 is in a refrigeration or defrosting working condition. The second filter 175 can filter the heat transfer agent flowing from the heat exchanger 140 into the evaporator 110 when the heating machine system 100 is in a heating working condition. In order to facilitate adjustment, the expansion valve 176 in the embodiment is an electronic expansion valve 176, of course, the expansion valve 176 can also be a manual expansion valve 176 or other expansion valves 176, which are not limited here.

[0045] Please continue to refer to Figure 2 , the heating machine system 100 in the embodiment further comprises a liquid accumulator 180, the inlet of the liquid accumulator 180 is communicated with the first outlet of the heat exchanger 140, and the outlet of the liquid accumulator 180 is communicated with the second filter 175. By arranging the liquid accumulator 180, it can help to stabilize the pressure inside the heating machine system 100, and the liquid accumulator 180 can buffer the flow fluctuation of the heat transfer agent in the system.

The low-pressure switch 192 is mainly used to monitor the state of the heating machine system 100 in the low-pressure environment, prevent the system from running in the low-pressure or unsuitable condition, and protect the system from being damaged. In order to facilitate the timely opening or closing of the high-pressure switch 191 and the low-pressure switch 192, the heating machine system 100 in the embodiment further comprises a first pressure sensor 193 and a second pressure sensor 194, the first pressure sensor 193 is arranged between the high-pressure switch 191 and the first valve port 131 of the four-way valve 130, and the second pressure sensor 194 is arranged between the third valve port 133 of the four-way valve 130 and the low-pressure switch 192.

[0047] In addition, in order to improve the precision of controlling the heat exchange efficiency of the heat exchanger 140, the heating machine system 100 in the embodiment further comprises an exhaust temperature probe 195 and a return air temperature probe 196, the exhaust temperature probe 195 is arranged at the outlet of the compressor 120, and the return air temperature probe 196 is arranged at the inlet of the compressor 120.

The centrifugal fan can push air to flow through the surface of the evaporator 110, enhance air flow, increase the contact area between air and the surface of the evaporator 110, and thus improve heat exchange efficiency. In this way, air can more effectively absorb the cold in the evaporator 110, helping to quickly reduce the air temperature. Moreover, by enhancing air flow, the centrifugal fan helps to reduce the condensation of moisture on the surface of the evaporator 110, reducing the occurrence of frost. In a low-temperature environment, frost can cause heat exchange efficiency to decrease, and the operation of the fan helps to keep the temperature of the surface of the evaporator 110 uniform, preventing ice and frost from accumulating. In addition, the centrifugal fan can also ensure that air flows uniformly on the surface of the evaporator 110 to improve the heat exchange efficiency of the evaporator 110. Moreover, the centrifugal fan can control the flow direction and speed of air, helping to form a more uniform distribution of cold air on the evaporator 110, avoiding the problem of local overcooling or overheating, and thus optimizing the temperature control and stability of the entire system.
