Abstract
A kind of with low boiling working fluid evaporation ends heat absorption evaporation produce low temperature for condensation end low-temperature heat source, by decompressor adiabatic expansion reclaim expansion work, not to the refrigerating method of environmental emission condensation heat.
Description
Technical field
The present invention relates to a kind of with low boiling working fluid sweat cooling as low-temperature heat source, reclaimed by decompressor and expand
Merit, not to the refrigerating method of environmental emission condensation heat.
Background technology
Heat is to cold transmission output work, but air-conditioning (heat pump) refrigeration the most not output work to consume energy on the contrary.Former
Under conditions of being that only single source exists, in order to realize kind of refrigeration cycle, it is necessary to put into work done during compression by work
Matter temperature is promoted on ambient temperature just to make the latent heat of working medium be released.The condensation heat that refrigeration produces is led to
Being often 1.1-1.3 times of refrigerating capacity, this is a reverse diabatic process, reverse according to the second law of thermodynamics
Input work is wanted in heat transfer.
It is refrigeration that air-conditioning is mainly applied, and condensation heat becomes the cost having to pay.Owing to condensation heat is low-grade
Heat utilization is worth low, is discharged into the most in vain in environment.If the discharge of condensation heat can be reduced or makes condensation
Heat is utilized effectively and just can improve air-conditioner efficiency, reduces energy consumption.
Summary of the invention
The present invention relates to a kind of not to the unidirectional refrigerating air conditioning device of environmental emission condensation heat, it is with power cycle
Mode is run, low as condensation end of low temperature produced from environment heat absorption evaporation at evaporation ends by low boiling working fluid
Temperature-heat-source, the interior merit that can be converted into working medium heat absorption obtained by decompressor is freezed.Owing to decreasing work done during compression
Put into and obtain expansion work, it is achieved thereby that energy-saving, even zero power consumption refrigeration.
The cyclic process of unidirectional refrigerating air conditioning device is as follows:
Evaporation endothermic: liquid phase working fluid enters vaporizer through working medium pump and absorbs heat carburation by evaporation from environment, it is thus achieved that interior energy.
Working medium heat absorption is refrigeration for by heat absorption object environment.
Adiabatic expansion: decompressor acting is adiabatic process, owing to cannot can only consume working medium certainly from external world's heat absorption
In body, energy, causes power pressure, temperature to decline.
Condensation heat release: the gas-phase working medium (temperature must be higher than working medium sweat cooling temperature) that decompressor is discharged enters
Low temperature that condenser produces with working medium sweat cooling and ambient temperature heat exchange, release latent heat of condensation liquefaction.
Adiabatic compression: liquid phase working fluid enters energy in vaporizer covers once again with environment heat exchange through working medium pump compression,
Enter subsequent cycle.
Above-mentioned circulation includes an endothermic process and two process of refrigerastions；Sweat cooling and swell refrigeration.System
With ambient temperature for high temperature heat source T1, the low temperature that working medium sweat cooling produces is low-temperature heat source T2, to expand system
Cold for refrigeration source.Low boiling working fluid absorbs heat and refrigeration (for endothermic object) equivalent at evaporation ends, swollen
Swollen machine adiabatic expansion (energy in consuming) output work and swell refrigeration equivalent.Working medium includes vapour in evaporation ends heat absorption
Changing latent heat and sensible heat, owing to the expanded machine of part sensible heat is converted into merit, working medium condensation heat release is certainly less than evaporation
Heat absorption Q2=Q1-W ＜ Q1, the condensation heat release circulated with existing air conditioner refrigerating is more than evaporation endothermic Q2=Q1+W ＞ Q1 phase
Instead.The low-temperature heat source that low temperature is condensation end produced in evaporation ends heat absorption evaporation due to working medium, therefore, as long as
Decompressor exhaust steam temperature out is ambient temperature higher than low-temperature heat source temperature, it is possible to make the condensation of exhaust steam
Latent heat has been released circulation, it is achieved that refrigeration is not to environmental emission condensation heat.

Detailed description of the invention
Run in power cycle mode, by low boiling liquid phase working fluid in evaporation ends heat absorption evaporation (to absorbed heat
Refrigeration for external environment condition) low temperature that produces as the low-temperature heat source of system condensing end, will by decompressor
The interior merit that can be converted into that working medium heat absorption obtains is freezed.
