When system works in heat pump cycle mode, large compressor (3) is opened, check valve (83, 84) be in conducting state, little compressor (4) cuts out, the second magnetic valve (72), check valve (81, 82) and return liquid capillary (9) be in cut-off state, large compressor (3) extracts gaseous working medium from evaporimeter (1) inside, become high-temperature high-pressure state by large compressor (3) gaseous refrigerant and carry to condenser (2), high temperature and high pressure gaseous refrigerant dispels the heat after entering condenser (2) in condenser (2), portion gas liquefies, gas-liquid two-phase cold-producing medium enters fluid reservoir (6) through condenser (2) catheter under the promotion of high-pressure gaseous refrigerant, gas-liquid refrigeration intermediate medium is separated in fluid reservoir according to respective physical property, high-pressure liquid intermediate medium enters into evaporimeter (1) through choke valve (5) and evaporimeter (1) catheter successively by the 4th check valve (84) and circulates next time.
When using heat-pipe refrigerating mode of operation, little compressor (4) is opened, the second magnetic valve (72), check valve (81, 82) and return liquid capillary (9) be in conducting state, large compressor (3) close, check valve (83, 84) cut-off state is in, condenser (2) contacts with low-temperature heat source, gaseous working medium is condensed into liquid by the cooling of low-temperature heat source in condenser (2), and release heat, the liquid-working-medium that condensation is formed is under the drive of little compressor (4), they enter into evaporimeter (1) from condenser (2), evaporimeter (1) contacts with high temperature heat source, liquid working media is evaporated to gas by the heating of high temperature heat source in evaporimeter (1), and absorb heat, the gas that evaporation is formed and the liquid intermediate medium that part is not evaporated mutually are mixed to form gas-liquid two-phase fluid in flow at high speed, they flow out from evaporimeter (1) and enter fluid reservoir (6) through the first check valve (81), gas-liquid two-phase flow intermediate working medium is separated in fluid reservoir according to respective physical property, gaseous state intermediate medium is delivered in condenser (2) by the second check valve (82) place branch road and is circulated next time, liquid intermediate medium passes through back liquid capillary (9) and exports, the liquid intermediate medium exported and converge from condenser (2) liquid intermediate medium out and enter into evaporimeter (1) through little compressor (4) simultaneously, so just form a kind of cyclic process of novel energy-conserving heat pipe, above-mentioned two kinds of circulations environmentally can carry out switch operating with demand.
embodiment two:
The workflow diagram of first scheme of the present invention as shown in Figure 4, described second magnetic valve (72), large compressor (3), condenser (2), fluid reservoir (6), the 4th check valve (84), choke valve (5) and evaporimeter (1) are linked in sequence according to above-listed by pipeline each other, constitute a heat pump cycle loop, described 5th check valve (85) is connected in parallel on large compressor (3), the output of little compressor (4) and the second magnetic valve (72) series arm and the output of the 4th check valve (84) and choke valve (5) series arm are all connected to the catheter of evaporimeter (1), their input is connected to fluid reservoir (6), then little compressor (4), second magnetic valve (72), evaporimeter (1), 5th check valve (85), condenser (2) and fluid reservoir (6) are linked in sequence according to above-listed by associated conduit, constitute a heat pipe closed circuit, these two circulations are environmentally carried out exchange work and are just constituted a kind of heat pipe hot pump hybrid system with demand like this.
When using heat pump refrigerating mode of operation, large compressor (3) is opened, first magnetic valve (71) and the 4th check valve (84) are in conducting state, little compressor (4) cuts out simultaneously, second magnetic valve (72) and the 5th check valve (85) are in closed condition, pressure is taken out due to large compressor (3), 5th check valve (85) place branch road does not almost have passing through of refrigeration working medium, such liquid condensation agent heat absorption in evaporimeter (1) reduces indoor temperature, liquid condensation agent after heat absorption becomes gaseous state, become high-temperature high-pressure state by large compressor (3) gaseous refrigerant and carry to condenser (2), high temperature and high pressure gaseous refrigerant enters heat radiation in condenser (2) after in condenser (1), portion gas liquefies, gas-liquid two-phase cold-producing medium enters fluid reservoir (6) through condenser (2) catheter under the promotion of high-pressure gaseous refrigerant, gas-liquid refrigeration intermediate medium is separated in fluid reservoir according to respective physical property, high-pressure liquid intermediate medium enters into evaporimeter (1) through choke valve (5) and evaporimeter (1) catheter successively by the 4th check valve (84) and circulates next time.
When using heat-pipe refrigerating mode of operation, little compressor (4) is opened, second magnetic valve (72) and the 5th check valve (85) are in conducting state, large compressor (3) cuts out, first magnetic valve (71) and the 4th check valve (84) are in closed condition, little compressor (4) is extracted a large amount of liquid refrigeration working medium and is supplemented a small amount of gaseous refrigerant working medium of whole stable circulation by the part of return-air hole (10) in fluid reservoir (6) simultaneously, successively through the second magnetic valve (72), evaporimeter (1) is entered with evaporimeter (1) catheter, evaporimeter (1) contacts with high temperature heat source, liquid working media is evaporated to gas by the heating of high temperature heat source in evaporimeter (1), and absorb heat, the gas that evaporation is formed and the liquid intermediate medium that part is not evaporated mutually are mixed to form gas-liquid two-phase fluid in flow at high speed, they are successively through evaporimeter (1) wireway, 5th check valve (85) and condenser (2) wireway enter condenser (2), condenser (2) contacts with low-temperature heat source, gaseous working medium is condensed into liquid by the cooling of low-temperature heat source in condenser (2), and release heat, condensation formed liquid-working-medium little compressor (4) take out pressure effect under, enter in fluid reservoir (6) through condenser (2) catheter, it carries out gas-liquid separation, store and shunting, circulate next time.
This like this heat pipe hot pump hybrid system can according to the difference of indoor required design temperature and outdoor temperature, optionally (it can complete Automatic Control, also can pass through to control to adjust duty manually) run on heat pump refrigerating mode of operation or heat-pipe refrigerating mode of operation, ensureing that the prerequisite that room temperature lowering requires is issued to energy-saving run; When outdoor temperature is higher or indoor load is excessive, heat pipe hot pump hybrid system operating heat pump refrigeration work pattern, operation principle is identical with general frequency conversion or non-frequency air-conditioning, and indoor heat is dissipated to the exterior space by vapor-compression refrigerant cycle, reaches the cooling down effect of the interior space; When outdoor temperature is lower than indoor temperature certain value, compressor cuts out, unit enters heat-pipe refrigerating mode of operation automatically, by heat pipe energy-saving module, gaseous refrigerant is brought to condensation heat release in condenser, finally become condensate liquid, condensate liquid absorbs heat at heat pipe energy-saving module flows by action to evaporimeter again, and whole system passes through heat pipe energy-saving module by indoor heat to outdoor transmission.
