Abstract
The utility model discloses a high -efficient heat pump water heater group of preventing frostbite, including the compressor, connect gradually heat exchanger and evaporimeter on the circulation pipeline of compressor, and connect choke valve between heat exchanger and the evaporimeter includes still that parallel connection is in little parallel transistor subassembly between heat exchanger and the choke valve, compressor, heat exchanger, little parallel transistor subassembly and choke valve connect gradually to constitute and heat the flow path, compressor and evaporimeter connection constitute the flow path of breathing in. Little parallel transistor unit mount in evaporimeter lower part, the choke valve of flowing through again, because the effect of little parallel transistor subassembly is greater than 0 through the back temperature of once throttling, so have frostproofing effect, in the frost -proof while, condensing temperature reduces, is favorable to improving the heat absorption capacity of evaporimeter. In addition, for traditional frostproofing heat pump water heater group, the utility model discloses a be parallelly connected pipeline a little to make the circulation pipeline of winner shorten greatly, promoted system's efficiency.
Description
Technical field
The utility model relates to heat pump water-heating machine technical field, more particularly, relates to a kind of high efficient antifreeze heat-pump hot-water unit.
Background technology
Heat pump water-heating machine is by marketing for many years, and large-scale popularization on northern market now, the energy saving of product has obtained the accreditation of user.
The condensed water of heat pump water-heating machine evaporimeter is all flow to down from above, and because evaporimeter bottom air quantity is little, evaporator temperature is low, when winter, current easily freeze through evaporimeter bottom, icing then can cause condensed water get rid of difficulty, and ice sheet because of impeded drainage can be more long-pending thicker.Fig. 1 is common a kind of antifreeze heat-pump hot-water unit solving this problem, comprise compressor 1, be connected to the heat exchanger 2 on the circulation line of compressor 1 and evaporimeter 3 in turn, and the choke valve 4 be connected between heat exchanger 2 and evaporimeter 3, also comprise the micro-tandem tube assembly 6 be connected in series between heat exchanger 3 and choke valve 4, compressor 1, heat exchanger 2, micro-tandem tube assembly 6 and choke valve 4 connect and compose successively and heat stream, and compressor 1 and evaporimeter 3 connect and compose air-breathing stream.Micro-tandem tube assembly 6 is installed to evaporimeter 3 bottom, then flows through choke valve 4, because effect temperature after a throttling of micro-tandem tube assembly 6 is greater than 0, therefore there is antifreezing effect, while antifreeze, condensation temperature reduces, and is conducive to the heat absorption capacity improving evaporimeter 3.But this structure can cause circulation line long, system pressure loss is comparatively large, is unfavorable for that efficiency promotes.
Utility model content
The purpose of this utility model is to overcome above-mentioned defect of the prior art, provide a kind of there is antifreezing effect and be conducive to system energy efficiency promote high efficient antifreeze heat-pump hot-water unit.
For achieving the above object, the technical scheme that provides of the utility model is as follows:
A kind of high efficient antifreeze heat-pump hot-water unit is provided, comprise compressor, be connected to the heat exchanger on the circulation line of compressor and evaporimeter in turn, and the choke valve be connected between described heat exchanger and evaporimeter, also comprise the micro-parallel transistor assembly be connected in parallel between described heat exchanger and choke valve, described compressor, heat exchanger, micro-parallel transistor assembly and choke valve connect and compose successively and heat stream, and described compressor and evaporimeter connect and compose air-breathing stream.
Wherein, described compressor is super low temperature heat pump compressor, and this super low temperature heat pump compressor has exhaust outlet and air entry.
Compared with prior art, the beneficial effects of the utility model are: a kind of high efficient antifreeze heat-pump hot-water of the utility model unit, micro-parallel transistor assembly is connected in parallel between heat exchanger and choke valve, micro-parallel pipeline is adopted to instead of traditional micro-series pipe, major cycle pipeline is shortened greatly, be conducive to system energy efficiency to promote, be still greater than 0 by effect temperature after a throttling of micro-parallel transistor assembly, there is antifreezing effect.
Below in conjunction with drawings and Examples, a kind of high efficient antifreeze heat-pump hot-water unit described in the utility model is described further.
Accompanying drawing explanation
Fig. 1 is the package assembly schematic diagram of traditional antifreeze heat-pump hot-water unit;
Fig. 2 is the package assembly schematic diagram of a kind of high efficient antifreeze heat-pump hot-water unit described in the utility model.
Detailed description of the invention
Be below the preferred example of a kind of high efficient antifreeze heat-pump hot-water unit described in the utility model, therefore do not limit protection domain of the present utility model.
Please refer to Fig. 2, there is shown a kind of high efficient antifreeze heat-pump hot-water unit, comprise compressor 1, be connected to the heat exchanger 2 on the circulation line of compressor 1 and evaporimeter 3 in turn, and the choke valve 4 be connected between described heat exchanger 2 and evaporimeter 3, also comprise the micro-parallel transistor assembly 5 be connected in parallel between described heat exchanger 3 and choke valve 4, described compressor 1, heat exchanger 2, micro-parallel transistor assembly 5 and choke valve 4 connect and compose successively and heat stream, and described compressor 1 and evaporimeter 3 connect and compose air-breathing stream.
During enforcement, micro-parallel transistor assembly 5 is installed to evaporimeter 3 bottom, then flows through choke valve 4, because effect temperature after a throttling of micro-parallel transistor assembly 5 is still greater than 0, therefore there is antifreezing effect, while antifreeze, condensation temperature reduces, and is conducive to the heat absorption capacity improving evaporimeter 3.In addition, relative to traditional antifreeze heat-pump hot-water unit, what the utility model adopted is micro-parallel pipeline, thus major cycle pipeline is shortened greatly, improves system energy efficiency.
Wherein, described compressor 1 is super low temperature heat pump compressor, and this super low temperature heat pump compressor has exhaust outlet and air entry.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
