Description

A kind of heat pipe hot pump hybrid system
Technical field
The invention belongs to cold and hot energy transporting technical field, relate to a kind of heat pipe hot pump hybrid system of carrying out cold and hot energy transporting that hot-pipe system is compounded to form mutually with heat pump system.
Background technology
For regulating and controlling the air-conditioning system chief component of environment temperature, be indoor heat exchanger and outdoor heat exchanger at present, this air-conditioning system can realize by the highly energy-consuming of compressor in indoor heat exchanger the temperature adjusting to condensing agent, thereby indirectly change indoor environment temperature, this air-conditioning system does not accomplish well to save the energy, when outdoor temperature is during lower than indoor temperature, because (extraneous dust concentration is large for certain reason, air pollution etc.) can not carry out direct cross-ventilation cooling by window opened via, the compressor of at this moment also having to open highly energy-consuming carries out temperature adjusting, this phenomenon is at high temperature dustproof environment (machine room, the special high temperature occasions such as electricity chamber) performance is obvious especially, because use occasion heat dissipation equipment is concentrated, heat dissipation capacity is large, space temperature is high, quick heating, prevent dust and require high characteristic, make to use traditional air-conditioning to be difficult to save energy here, even also have to when outdoor temperature is more much lower than indoor temperature, start heat pump cooling, and now relative energy-saving a kind of introduces the mode that all-fresh air lowers the temperature a lot of areas is inapplicable at home, can a large amount of outdoor dust and humid air be brought into indoor, the safety that affects indoor equipment is normally moved.
The form of the another kind of wind that adopts---wind heat exchanger can avoid outdoor dust and humid air to introduce indoor, but need on the safeguard structures such as equipment room, machine room enclosure wall, offer larger ventilation hole, not only destroy the stability of body of wall, also have stolen potential safety hazard.
Some season throughout the year, as winter and spring and autumn, in the situation that outdoor temperature is lower and can not carry out indoor-outdoor air convection current than the design temperature in indoor heat release region, the compressor that does not also have a kind of system can need not open in this case highly energy-consuming just can carry out indoor temperature control, even in this case, the compressor that existing air-conditioning system must start highly energy-consuming particularly those caloric values is concentrated and is required high workplace to control temperature to environment to cleannes, it is this that still adopt heat pump to lower the temperature to carry out cooling scheme be not energy-conservation, thereby the unnecessary waste that causes electric energy, operation costs are high.
Summary of the invention
The object of the invention is to overcome the shortcoming that prior art exists, for solving the large problem of energy consumption existing in heat pump, and provide a kind of simple in structure, implement easily, the heat pipe hot pump hybrid systems of energy-saving and emission-reduction, can under the suitable condition of outdoor temperature, automatically enable energy saver mode and regulate indoor temperature, can be safely, reliable, stable, the energy-conservation automatic running refrigerating circulatory system.
technical solution problem of the present invention adopts following technical scheme:
A hybrid system, mainly comprises condenser, evaporimeter, large compressor, Two-phase fluid pump, two-phase current divider, magnetic valve, check valve one, check valve two, choke valve, fluid reservoir, wireway, catheter and circuit controling element; Described condenser and evaporimeter are the micro-channel heat exchangers of aluminum; Described Two-phase fluid pump is the little compressor of positive displacement that can simultaneously carry gas and liquid; Described condenser output is positioned at the top of fluid reservoir liquid refrigerant liquid level, and choke valve liquid feeding end is positioned at the bottom of fluid reservoir liquid refrigerant liquid level; So large compressor, condenser, fluid reservoir, check valve one, choke valve, evaporimeter are linked in sequence according to above-listed by pipeline each other, have formed a heat pump cycle loop; Described check valve two is connected in parallel on large compressor; The output of branch road and the output of check valve one and choke valve series arm of described Two-phase fluid pump, magnetic valve and the series connection of two-phase current divider are connected in evaporimeter catheter by three-way pipe one, and their input is connected in liquid storage and fills with; Two-phase fluid pump, magnetic valve, evaporimeter, check valve two, condenser and liquid storage are filled with and are linked in sequence according to above-listed by connecting pipe like this, have formed a heat pipe circulatory system; When described heat pipe hot pump hybrid system is worked in heat pump cycle mode, large compressor is opened, and check valve one is in conducting state, and Two-phase fluid pump is closed simultaneously, and magnetic valve and check valve two are in closed condition; When described heat pipe hot pump hybrid system is worked in heat pump cycle mode, Two-phase fluid pump is opened, and magnetic valve and check valve two are in conducting state, and large compressor cuts out, check valve one is in cut-off state, and above-mentioned two kinds of circulations can be carried out switch operating according to environment and demand.
The above circuit controling element comprises the control circuit of heat pump refrigeration system and the control circuit of heat pipe heat exchanging system, can, according to the contrast of indoor design temperature and outdoor temperature, make heat pump refrigeration system and heat pipe heat exchanging system carry out automation and control switching.
The present invention compared with prior art, separate heat pipe technology and steam compression type refrigeration technology are merged mutually, have complementary advantages, make full use of the power-saving technology of natural cooling source, when indoor required design temperature is lower than outdoor temperature, by heat pump cycle, carry out radiating and cooling, when indoor required design temperature is higher than outdoor temperature, by heat pipe, loop radiating and cooling, for throughout the year, have that to exceed time of 2/3rds be that outdoor temperature is lower than indoor required design temperature, like this under heat pipe energy-saving pattern, the large compressor of highly energy-consuming is without startup, only with the heat pipe energy-saving module and the blower fan that start low power consuming, energy consumption is extremely low, under refrigeration mode, advantage due to two kinds of Refrigeration Technique plyability designs, make refrigeration efficiency than being better than general air-conditioning, energy-saving effect is remarkable, and this heat pipe hot pump hybrid system can be applied to the heat radiation temperature control in the fields such as base station, machine room and large electric appliances equipment.
