Description
Technical Field
The invention relates to the technical field of refrigeration, in particular to a heating type refrigeration cycle method and a device thereof.
Background
In the technical field of refrigeration, all the devices for realizing reverse Carnot cycle refrigeration adopt a vapor compression refrigeration cycle. The theoretical cycle of vapor compression refrigeration consists of two isobaric processes, an adiabatic compression process and an adiabatic throttling process. Namely, an adiabatic compression process → an isobaric heat release process → an adiabatic throttling process → an isobaric heat absorption process, and the four processes form a refrigeration cycle.
The high-temperature refrigerant vapor and the cooling medium have temperature difference, can release heat to the cooling medium (high-temperature heat source) and is beneficial to condensing into liquid; the high pressure refrigerant vapor establishes a pressure differential between the condenser and the evaporator, the resistance to flow of refrigerant therebetween can be overcome and the high pressure refrigerant vapor facilitates condensation of the refrigerant to a liquid at the condenser. However, the vapor compression refrigeration cycle is realized by a method of mechanically compressing refrigerant vapor using a mechanical device (compressor) to complete an adiabatic compression process to produce a high-temperature and high-pressure refrigerant vapor heat source, and has several disadvantages: on one hand, the loss caused by self factors is as follows: 1, friction of refrigerant vapor in a compressor, gas inside and between the gas and a cylinder wall, and heat exchange of the gas and the outside; 2, loss of refrigerant flowing through the compressor suction valve and the compressor exhaust valve; the second aspect is the loss caused by energy conversion, the compressor converts the electric energy into the mechanical energy firstly, then converts the mechanical energy into the heat energy, and the two conversions have large loss. The third aspect is that the valve ports of the suction valve and the exhaust valve of the compressor are too small, and the complex structure in the compressor obstructs the communication between the evaporator and the condenser to cause loss: 1, since the valve port of the compressor suction valve is too small to make the evaporator outlet in abutment therewith too small, the refrigerant liquid is too small at the free surface of the evaporator, thereby inhibiting the generation of refrigerant liquid vaporization conditions. The heat of the cooled medium can not be fully utilized to promote the heat absorption, evaporation and vaporization of the refrigerant liquid; 2, the valve port of the exhaust valve of the compressor is too small, so that the inlet of the condenser which is butted with the valve port is too small, and the flow resistance of the refrigerant vapor entering the condenser is too large; 3, because the complex structure in the compressor obstructs the communication between the evaporator and the condenser, the refrigerant vapor at the outlet of the evaporator can not make random thermal motion through gas molecules to reach the condenser. Otherwise, there is a power supply loss for the actual compressor motor power factor of less than 100%. Therefore, the mechanical compression method adopted to produce the high-temperature and high-pressure refrigerant vapor heat source can make the compressor do a lot of useless work, and the heat of the cooled medium cannot be fully utilized to promote the refrigerant liquid in the evaporator to absorb heat, evaporate and vaporize, so that the efficiency of the vapor compression refrigeration cycle system is low, and the energy consumption of the vapor compression refrigeration cycle device is high.
Disclosure of Invention
The present invention is directed to overcome the above-mentioned shortcomings of the prior art, and to provide a heating type refrigeration cycle method, which solves the problem of low efficiency of the refrigeration cycle system caused by the mechanical compression method of the compressor used in the compression process of the vapor compression type refrigeration cycle system to produce the high-temperature and high-pressure refrigerant vapor heat source, and the problem of high energy consumption of the vapor compression type refrigeration cycle device. Meanwhile, according to the heating type refrigeration cycle method, the embodiment of the invention provides a heating type refrigeration cycle device 100.
In order to achieve the purpose, the technical scheme of the invention is as follows:
in one aspect, the present invention provides a heating type refrigeration cycle method including the steps of:
s1 adiabatic heating process
The heater carries out heat insulation heating on the low-temperature low-pressure refrigerant vapor at the outlet of the evaporator to obtain high-temperature high-pressure refrigerant vapor;
s2 isobaric condensation heat release process

s4 isobaric evaporation endothermic process
The evaporator evaporates the low-temperature low-pressure refrigerant liquid at the outlet of the throttling device in an isobaric manner to obtain low-temperature low-pressure refrigerant vapor and absorb the heat of the cooled medium;
steps S1 to S4 constitute a refrigeration cycle.
In another aspect, an embodiment of the present invention provides a heating type refrigeration cycle apparatus 100, following the heating type refrigeration cycle method described above. The heating refrigeration cycle apparatus 100 mainly includes: evaporator 10, heater 20, condenser 30 and throttling device 40.
The refrigerant outlet of the evaporator 10 is communicated with the refrigerant inlet of the heater 20, the refrigerant outlet of the heater 20 is communicated with the refrigerant inlet of the condenser 30, the refrigerant outlet of the condenser 30 is communicated with the refrigerant inlet of the throttling device 40, the refrigerant outlet of the throttling device 40 is communicated with the refrigerant inlet of the evaporator 10, and the evaporator, the heater, the condenser and the throttling device form a refrigerant circulation loop; wherein,
the evaporator 10 is a heat exchanger.
In the evaporator 10, the refrigerant outlet is open, and the number of refrigerant outlet connecting pipes is at least one; the refrigerant outlet connecting pipe is connected in a welding mode, a flange connection mode or a threaded connection mode.
And a heat insulation material is laid on the outer side of the heater 20.
The heater 20 is an air duct type heating device, and is used for heating the refrigerant in the circulation loop.
The heater 20 is arranged in the air duct or outside the air duct; the heating body is a fluid heating coil or an electric heating tube.

The adiabatic compression process of the vapor compression refrigeration cycle is replaced by the adiabatic heating process, and the mode of mechanically compressing the refrigerant vapor to manufacture the high-temperature high-pressure heat source is replaced by the mode of directly heating the refrigerant vapor at the outlet of the evaporator to manufacture the high-temperature high-pressure heat source, so that the replacement of the compressor by the heater is completed. Moreover, because the heater replaces the compressor, the refrigerant outlet area of the evaporator is large enough, the refrigerant liquid of the evaporator obtains large enough free surface and can utilize the heat of the cooled medium to the maximum extent to promote the heat absorption evaporation of the refrigerant liquid in the evaporator. Meanwhile, the heater replaces the compressor, so that the condenser obtains enough large refrigerant inlet area, and the flow resistance of the refrigerant vapor entering the condenser is greatly reduced. In addition, because the heater replaces a compressor, refrigerant vapor from the evaporator does irregular heat movement through gas molecules, the refrigerant vapor can reach the condenser through the heater without heating expansion, and the heat is transferred between the evaporator and the condenser automatically. Therefore, the heater can replace the compressor to realize low energy consumption of the heating refrigeration cycle device. Meanwhile, the heater has no moving parts, so that the heater has no mechanical abrasion, and has no vibration, no noise and the like in the operation process.
