The specific embodiment
Referring to Fig. 1,, heating is improved in order to improve the cryogenic refrigeration ability.The compressor 6 that is adopted increases the enthalpy compressor for tonifying Qi, heating capillary is by heating capillary a13, heat capillary b15 and heat capillary c12 and constitute, heat capillary a13 and heat capillary c12 and be arranged in parallel, heat capillary b15 and heat capillary a13 and heat the capillary c12 setting of connecting, be provided with magnetic valve B19 at an end that heats capillary c12, heating capillary a13, heat capillary c12 and heat between the capillary b15 and be connected with gas-liquid separator 14 by working medium tube 7, gas-liquid separator 14 gaseous states outlets is communicated with the gas supplementing opening 6-1 that increases enthalpy compressor 6 in tonifying Qi by working medium tube 7, increases between the enthalpy compressor air suction mouth in the outlet of gas-liquid separator 14 gaseous states and tonifying Qi magnetic valve A17 is housed.
Kind of refrigeration cycle is still continued to use existing circuit cycle.
Move according to diagram refrigeration arrow route in the time of refrigerating operaton, the refrigerant steam of the HTHP of discharging from compressor 6 becomes high-pressure sub-cooled liquid through condenser 18, enter evaporimeter 8 evaporations and become overheated gas from external world's heat absorption and get back to compressor 6 through crossing check valve 10 after the refrigerating capillary 11 throttling step-downs again, form circulation, the compressor 6 middle gas supplementing opening 6-1 magnetic valve A17 of place close during kind of refrigeration cycle.
During heating operation, if ambient temperature is higher than 0 ℃, 8 condensations become highly pressurised liquid to the high temperature and high pressure gas of discharging from compressor 6 through the diagram evaporimeter, enter a special gas-liquid separator 14 through heating capillary a13 throttling becoming liquid-vapor mixture, this moment with heat the magnetic valve B19 that capillary c12 connects and close, heat not participation system circulation of capillary c12, the refrigerant of this moment is punished into two-way at gas-liquid separator, the refrigerant on gas-liquid separator 14 tops enters compressor 6 through magnetic valve A17 and replenishes gaseous coolant for compressor 6, and refrigerant temperature in the reduction compressor, with raising compressor 6 compressed capabilities, and reduce compressor 6 delivery temperatures.
