The isenthalpic heat exchange means heat exchange with a constant enthalpy value. The enthalpy compressor in the scheme is essentially a combination of a common heat exchanger and a common compressor, namely, the enthalpy heat exchange of the heat exchanger + the compression formed by the gas compressor = the enthalpy compression in the common sense. Isenthalpic compression is a thought controlled compression process, and adopts ideal gas (i.e. molecules are elastic particles which do not occupy volume, no force is generated between molecules except collision, and the ideal gas is an abstraction of actual gas at low pressure and high temperature), which cannot absolutely reach isenthalpic and only tends to isenthalpic.
Further, the isenthalpic compressor 1, which is a modified form of a general compressor, is a high temperature resistant or split type compressor. And the ordinary compressor and the heat exchanger which form the isenthalpic compressor 1 need to adopt heat preservation measures, and the heat preservation layer is wrapped outside the ordinary compressor and the heat exchanger.
Furthermore, the application range of the scheme is various artificial environment equipment needing the compressor, including air conditioners, water heaters, heat pumps, water chilling units, freezing and refrigerating warehouses, municipal heating and the like.
The high-efficiency refrigerating and heating equipment consists of an isenthalpic compressor 1, a heat regenerator 2, an evaporator 3, a throttle valve 4 and a condenser 5, and the working method comprises the following steps:
A. in a cold working condition, high-pressure high-temperature gas flows out of an outlet at a high-pressure end of the isenthalpic compressor 1, the high-pressure high-temperature gas enters the condenser 5 to release heat to form high-pressure medium-temperature gas, the high-pressure medium-temperature gas enters the heat regenerator 2 to be cooled to form high-pressure normal-temperature liquid, the high-pressure normal-temperature liquid enters the throttle valve 4 to be throttled and depressurized to form a medium-pressure and high-pressure normal-temperature gas-liquid mixture, the gas-liquid mixture enters the evaporator 3 to be gasified to form low-pressure low-temperature gas, the low-pressure low-temperature gas enters the heat regenerator 2 to be subjected to heat exchange to form low-pressure normal-temperature gas, and the low-pressure;

Example 1, ultra-high energy efficiency air conditioner:
in severe cold areas with the temperature lower than minus 20 ℃, ordinary air-conditioning heating cannot be used, the auxiliary heating of enhanced vapor injection and electricity is adopted in a small amount, the power consumption is high, and the effect is not ideal. In this embodiment 1, an efficient cooling and heating apparatus is proposed, which is not only suitable for severe cold regions, but also widely applicable to cooling and heating air conditioners, ground source heat pumps, water source heat pumps, air source water heaters, and water chilling units under various climatic conditions, and the specific method is as follows: the original compressor in the system is replaced by an isenthalpic compressor which is formed by a high-temperature-resistant compressor connected with a heat exchanger in series, as shown in figure 1, a throttle valve 4 is connected with the input end of an evaporator 3, the output end of the evaporator 3 is connected with the low-temperature end inlet of a heat regenerator 2, the low-temperature end outlet of the heat regenerator 2 is connected with the low-pressure end inlet of the isenthalpic compressor 1, the high-pressure end outlet of the isenthalpic compressor 1 is connected with the inlet of a condenser 5, the output end of the condenser 5 is connected with the high-temperature end inlet of the heat regenerator 2, and the high-temperature end outlet of the heat regenerator 2 is connected with the; because the common compressor is changed into the isenthalpic compressor, the tasks of hot compression and potential energy lifting are separated, the hot compression is completed by the heat exchanger, and the potential energy lifting is completed by the compressor.
Taking a super heating air conditioner as an example, working in a severe cold area with 20 ℃ below zero, a refrigerant R134a is adopted as a working medium, the temperature of a condenser is set to be 60 ℃, the supercooling degree is 5 ℃, the corresponding condensation pressure of a pressure-enthalpy diagram is 1.8MPa at the condensation temperature of 60 ℃, the outlet pressure of an evaporator is 0.135MPa at the outlet temperature of-20 ℃, in order to further improve the heating efficiency, a regenerator is added, the inlet of the high-temperature end of the regenerator is connected with the output end of the condenser, the outlet of the high-temperature end of the regenerator is connected with the inlet end of a throttle valve 4, the inlet of the low-temperature end of the regenerator is connected with the outlet of the evaporator, the outlet of the low-temperature end of the regenerator is connected with the inlet of an isenthalpic compressor, the regenerator mainly increases the superheat degree of the outlet of the evaporator, the refrigeration and heating capacity of the unit refrigerant is, the outlet of the low temperature end of the heat regenerator is 50 ℃, if an isenthalpic compressor is not adopted, the inlet temperature of the compressor is the inlet temperature of the compressor, the compressor needs to lift gas with 0.135MPa, 50 ℃ and 450KJ/kg of enthalpy to 1.8MPa, 140 ℃ and 520KJ/kg of enthalpy, electric power consumption of each 1kg of the compressor is 70KJ, under the working condition, the heating capacity of each 1kg of working medium is 240KJ, and according to the definition of energy efficiency ratio, the heating capacity is divided by the power consumption of electricityThe rate 240KJ ÷ 70KW =3.43, which is a result achieved only with the use of a regenerator, but the compressor temperature has reached 140 ℃, exceeding the compressor protection temperature. After the isenthalpic compressor is adopted, the inlet of the isenthalpic compressor is still 0.135MPa, the temperature is 50 ℃, the outlet temperature of the compressor body is still 140 ℃, but the outlet temperature of the isenthalpic compressor, namely the outlet temperature of the heat exchanger is 80 ℃, the heating capacity is reduced to 170KJ/Kg, the increase value of the pressure is 1.8MPa-0.135MPa =1.665MPa, the increase value is converted into Kg and is equal to 16.65Kg, and 1KW =102 N.m, so the increase potential energy = mg/102 =16.65Kg × 9.8m/s2÷102=1.6KW。
From the above data, it is clear that, when the same supercharging function is realized, the energy efficiency ratio of consumption of the isenthalpic compression is 170KW/1.6KW =106, the compressor efficiency is 0.5, the energy efficiency ratio can also reach 50, and the energy saving effect is extremely remarkable.
Of course, to achieve this effect, a very rigorous process is necessary: because 18KW ÷ 1.35KW =13, need to raise the pressure ratio of the compressor to about 11-13, because of using the heat regenerator and increasing the compression ratio, the temperature of the compressor will obviously raise, and need to take the heat-insulating measure in order to guarantee very high energy efficiency ratio compressor and heat exchanger, this will exceed its protective temperature to making the apparatus that integrates motor and compressor into at present, so compressor and motor must make split type, make the integration into compressor and motor at present, the purpose is to reduce the noise and facilitate the lubrication, after making the split type, the compressor only needs to adopt appropriate material and lubricating oil can bear the higher temperature, the motor lubricates very common things independently, because the pressure and motor power that the compressor bears actually reduce a lot, as long as the problem of dealing with the noise is very good to solve, while the compressor takes the heat-insulating treatment, the noise thereof is also reduced;
also, to ensure an improvement in the energy efficiency ratio, the connecting piping between the heat exchanger of the isenthalpic compressor and the compressor must be shortened as much as possible.
The regenerator and the isenthalpic compressor are the best isenthalpic enthalpy increasing technology, so the enhanced vapor injection compressor is not needed.
The power of the corresponding compressor motor can be greatly reduced.
The heating air conditioner is used for refrigeration, the working condition is greatly improved, and the refrigeration energy efficiency ratio is similar to that of heating.
On the basis of the scheme of the embodiment, under the condition that the refrigerating and heating temperature difference is small, a heat regenerator can be omitted, as shown in fig. 2, a throttle valve 4 is connected with the input end of an evaporator 3, the output end of the evaporator 3 is connected with the inlet of the low-pressure end of an isenthalpic compressor 1, the outlet of the high-pressure end of the isenthalpic compressor 1 is connected with the inlet of a condenser 5, and the output end of the condenser 5 is connected with the throttle valve 4; because the common compressor is changed into the isenthalpic compressor, the tasks of hot compression and potential energy lifting are separated, the hot compression is completed by the heat exchanger, and the potential energy lifting is completed by the compressor.
Example 2, ultra-efficient water heater:
the structure is the same as that of a heating air conditioner, as shown in figure 1, except that a condenser in the air conditioner is replaced by a condenser in a water storage tank;
the national standard stipulates that the hot water temperature is not lower than 55 ℃, so the condensation temperature of the ultra-efficient water heater is set to be 60 ℃, and the condensation temperature is equal to the condensation temperature of the ultra-efficient water heater
The condensing temperature set by the heating air conditioner is the same, so the working condition is also suitable for the ultra-high efficiency water heater, when the water temperature is close to 60 ℃, the compressor stops working, and when the water temperature is reduced to 45 ℃, the compressor resumes working, thereby keeping stable hot water supply.
The life hot water is needed all the year round, and the hot water can be used for heating in winter, so that the water heater has wide application.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
