Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In view of the problems in the prior art, the present invention provides an air conditioner, a heat pipe defrosting control method, a computer device, a medium and a terminal, and the present invention is described in detail below with reference to the accompanying drawings.
The compressor of the air conditioner outdoor unit can generate a large amount of heat energy in the running process. The heat pipe evaporation section is used for absorbing heat from the compressor cylinder body, and the heat is transferred to the base plate through the heat pipe condensation section and is used for melting frost on the base plate of the outdoor unit.
As shown in fig. 1-2, a heat pipe defrosting air conditioner provided by an embodiment of the present invention includes:
in the heating cycle of the air conditioning system, low-temperature and low-pressure refrigerant gas is compressed into high-temperature gas by the compressor 1, then the high-temperature and high-pressure refrigerant gas reaches the indoor evaporator 5 through the four-way valve 2, and the refrigerant flows in the evaporator and transfers heat to the indoor space through convection heat exchange. The low-temperature high-pressure refrigerant passes through the throttling device 4, the pressure is reduced, and the low-temperature gas is liquefied into low-temperature liquid. The low-temperature liquid flows into the outdoor condenser 3, absorbs the heat outside through convection heat exchange, evaporates into low-temperature gas, and then enters the compressor-1 for continuous circulation, as shown in the attached figure 1.
Secondly, after the circulation of the air conditioning system starts, the compressor continuously compresses and does work, and the surface temperature of the cylinder body of the compressor can continuously rise. In the invention, the heat pipe evaporation section 61 of the heat pipe assembly 6 arranged on the outer surface of the compressor can be arranged on the middle upper part of the compressor in a ring shape, see the attached figure 2, the reason for the arrangement on the middle upper part of the compressor is that: under the condition of low temperature, the fluidity of the refrigerant and the lubricating oil is reduced, a large amount of refrigerant and lubricating oil can be gathered at the bottom of the compressor, and the temperature at the bottom of the compressor is slowly increased and has low increasing amplitude compared with the middle upper part of the compressor in the operation process of the compressor.
After the heat pipe evaporation section 61 absorbs the heat on the surface of the compressor shell, the working liquid in the heat pipe absorbs the heat and boils to be vaporized, the steam with a large amount of heat energy enters the heat pipe condensation section 63 through the heat pipe insulation section 62, and the working liquid in the heat pipe condenses and releases the heat at the heat pipe condensation section to transfer a large amount of heat and cold out. The heat pipe condensation sections 63 are distributed on the primary drainage plane (i.e. the surface of the chassis parallel to the drainage hole) of the outdoor unit chassis in a dispersed and diffused manner, as shown in fig. 2.
The invention can realize the melting effect of the outdoor unit chassis frost at low temperature by utilizing the heat source in the air conditioning system and the energy transfer function of the heat pipe assembly without energy consumption, can melt the frost condensed on the chassis by condensed water on a condenser during heating operation, and can melt the frost condensed by rain and snow accumulated on the outdoor unit chassis and rapidly dropped in heavy snow weather.
The invention also comprises a control scheme of the heat pipe defrosting air conditioning system.
The traditional chassis electric heating belt and the chassis electric heating pipe are opened when the outdoor environment temperature is lower than a certain value, and are in linkage control with the compressor.
The heat pipe defrosting air conditioning system and the control scheme thereof can also solve the problem that rain and snow falling rapidly are accumulated on the outdoor unit chassis and fan blades are broken by accumulated snow on the chassis after a fan is started in a long-time power-off or shutdown state which cannot be solved by the traditional chassis electric heating belt and the electric heating pipe.
The control scheme flow chart is shown in figure 3.
Description of various parameters in the flow:
a. outdoor ambient temperature Ta: defined as the heat pipe assembly start-up temperature, Ta, for example, may be defined as-1 deg.c.
b. Compressor continuous run time t 1: the non-stop running time of the compressor is defined as t1 which can be defined as 15 min.
c. Compressor upper cylinder temperature Tc: defined as the heat pipe assembly design action temperature, e.g., Tc may be defined as 50 ℃ by design.
d. And (4) delaying the starting time of the fan t3, wherein the delayed starting time of the fan is defined as 3min under a specific condition, such as t 3.
The detailed flow chart is described as follows:
the air conditioner receives a remote controller heating operation signal or is in a heating mode, which is mainly divided into two cases, the first case is that the air conditioner is always in heating operation but the outdoor temperature is continuously reduced, for example, at night in winter. In the second case, the air conditioner is not started to operate and is just started.
And secondly, detecting the outdoor environment temperature at the moment, and defining that the starting condition of the heat pipe assembly is met when the outdoor environment temperature is less than Ta.
And thirdly, whether the compressor is started or not is continuously detected, if the compressor is started, the compressor belongs to the first condition of the first point and is in heating operation. If not, belonging to the second condition, just starting up to run heating.
And fourthly, under the first condition, whether the outer fan is started or not is continuously detected, if yes, if the upper temperature of the compressor cylinder meets the condition that the temperature is more than Tc, the heat pipe assembly starts to work, after the heat pipe evaporation section 61 absorbs the heat on the surface of the compressor shell, the working liquid in the heat pipe absorbs the heat and boils and then vaporizes, the steam carries a large amount of heat energy to enter the heat pipe condensation section 63 through the heat pipe heat insulation section 62, and the working liquid in the heat pipe condenses and releases the heat at the heat pipe condensation section to transfer a large amount of heat and cold. The heat pipe condensation sections 63 are distributed on the primary drainage plane (i.e. the surface of the chassis parallel to the drainage holes) of the outdoor unit chassis in a dispersed and diffused manner.
And in the second situation, continuously detecting whether the external fan is started, if not, increasing the delayed starting time t3 of the fan when the fan is not started in order to solve the problem that rain and snow falling rapidly are accumulated on the chassis of the outdoor unit in the long-time power-off or shutdown state. If the upper temperature of the compressor cylinder meets the condition that the temperature is more than Tc, the heat pipe assembly starts to work, after the heat pipe evaporation section 61 absorbs the heat on the surface of the compressor shell, the working liquid in the heat pipe absorbs the heat and boils, then the working liquid is vaporized, the steam carries a large amount of heat energy to enter the heat pipe condensation section 63 through the heat pipe heat insulation section 62, and in the heat pipe condensation section, the working liquid in the pipe condenses and releases the heat, so that a large amount of heat and. The heat pipe condensation sections 63 are distributed on the primary drainage plane (i.e. the surface of the chassis parallel to the drainage holes) of the outdoor unit chassis in a dispersed and diffused manner.
The frost condensed on the chassis by the condensed water on the condenser during heating operation can be melted by the heat released by the heat pipe condensation section 63, and the frost condensed by rain and snow accumulated on the chassis of the outdoor unit and falling rapidly in heavy snow weather can also be melted. Therefore, the phenomenon that frost on the chassis is accumulated and raised continuously and collides with the running fan blades to cause damage of the fan blades and incapability of running can be avoided.
According to the invention, a further embodiment can be derived:

And thirdly, whether the compressor is started or not is continuously detected, if the compressor is started, the compressor belongs to the first condition of the first point and is in heating operation. If not, belonging to the second condition, just starting up to run heating.
And fourthly, under the first condition, whether the outer fan is started or not is continuously detected, if yes, if the upper temperature of the compressor cylinder meets the condition that the temperature is more than Tc, the heat pipe assembly starts to work, after the heat pipe evaporation section 61 absorbs the heat on the surface of the compressor shell, the working liquid in the heat pipe absorbs the heat and boils and then vaporizes, the steam carries a large amount of heat energy to enter the heat pipe condensation section 63 through the heat pipe heat insulation section 62, and the working liquid in the heat pipe condenses and releases the heat at the heat pipe condensation section to transfer a large amount of heat and cold. The heat pipe condensation sections 63 are distributed on the primary drainage plane (i.e. the bottom plate surface parallel to the drainage holes) of the outdoor unit chassis and the bottom of the condenser in a dispersed and diffused manner.
And in the second situation, continuously detecting whether the external fan is started, if not, increasing the delayed starting time t3 of the fan when the fan is not started in order to solve the problem that rain and snow falling rapidly are accumulated on the chassis of the outdoor unit in the long-time power-off or shutdown state. If the upper temperature of the compressor cylinder meets the condition that the temperature is more than Tc, the heat pipe assembly starts to work, after the heat pipe evaporation section 61 absorbs the heat on the surface of the compressor shell, the working liquid in the heat pipe absorbs the heat and boils, then the working liquid is vaporized, the steam carries a large amount of heat energy to enter the heat pipe condensation section 63 through the heat pipe heat insulation section 62, and in the heat pipe condensation section, the working liquid in the pipe condenses and releases the heat, so that a large amount of heat and. The heat pipe condensation sections 63 are distributed on the primary drainage plane (i.e. the bottom plate surface parallel to the drainage holes) of the outdoor unit chassis and the bottom of the condenser in a dispersed and diffused manner.
