Abstract

The utility model relates to a returning air compensator for refrigerating equipment and heating equipment, which solves the technical issue that allocating a compensation piece in the heating equipment system, so as to improve the working situation of equipment and increase the heating producing efficiency of the system; moreover, the compensation piece is simple in structure, easy in manufacture and low in cost. The utility model has a technical proposal that: the refrigerating equipment and heating equipment adopt a heat recovery compensator which contains an inner tube and an outer tube, wherein, the outer tube is longer than the inner tube and is sleeved on the inner tube; a certain distance is left between the outer circumferences of the inner tube and the outer circumferences of the outer tube; the two circular ends of the outer tube are sealed first and then have an entrance and an exit respectively; the entrance of the outer tube is connected to the exit of exchanger of an outer machine; the entrance of the outer tube is connected to the sucking interface of the compressor; one end of the inner tube opposite to the entrance of the outer tube is an exit which is connected to the entrance of the outdoor machine entrance; and the other end of the inner tube is an entrance connected to the exit end of the outdoor machine exchanger. The shape of the compensator can be made to a U shape or a circular shape.

Description

Heating-cooling equipment recuperation of heat compensator

Technical field

The utility model relates to the parts of a kind of refrigeration, heating equipment, the return-air compensator of especially all kinds of air-conditionings, air source, heat pump and energy-conserving and environment-protective air-conditioning system.

Background technology

As everyone knows, the hot equipment of refrigeration such as present air-conditioning, air source, heat pump and all kinds of environmental protection and energy saving air-conditionings are when temperature is lower than-5～10 ℃ in the winter time, the ability to work of this machine usefulness descend (this is that the particularity in the employed cold-producing medium fluorine of all machines Lyons at present itself determines) that will cause because of the interchanger frosting of off-premises station absorbing heat.

For addressing this problem, respectively manufacture producer at present and mainly take dual mode to solve outer machine defrost problem: the one, the system inner refrigerant of utilization is swung to and is flowed defrost, and the 2nd, utilize the auxilliary heat of electricity to come defrost.No matter take which kind of mode, when temperature was lower than-5～-10 ℃ in the winter time, the hot device systems inside of freezing all also needed to augment the problem that the auxilliary heat of electricity remedies the inefficiency in winter.This not only will expend extra energy, and the configuration of equipment is also too complicated, causes operating cost big, and electricity is assisted characteristics such as fragile.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of compensating unit of configuration in the hot device systems of refrigeration to improve equipment working condition, improves system's heating efficiency; And the compensating unit that is disposed should be simple in structure, and is easy to manufacture, with low cost.

The technical scheme that the utility model provides is: heating-cooling equipment recuperation of heat compensator, pipe and outer tube in this compensator comprises, the length of outer tube is less than interior pipe, outer tube sleeve on inner pipe and the outer circumference surface of the inner peripheral surface of outer tube and interior pipe keep certain spacing, be beneficial to the circulation of gas-liquid; After the annular end sealing at the two ends of outer tube, two ends are respectively equipped with import and outlet again; The import of outer tube connects with the outlet of off-premises station interchanger, and the outlet of outer tube connects with the air-breathing interface of compressor; End corresponding to the import of outer tube of interior pipe is outlet, links with the import of off-premises station interchanger; The other end of interior pipe is import, connects with the port of export of indoor set interchanger.

This heating-cooling equipment can be made into U-shaped or annular with the shape of compensator.

The beneficial effects of the utility model are: when temperature is lower than below-5～-10 ℃ in the winter time, the import of pipe utilizes the outlet waste heat of indoor set interchanger in this compensator, make the heating of gasifying rapidly of low-temp low-pressure liquid in off-premises station interchanger and the compressor air suction section, cryogenic liquid is boosted by gasification, thereby improved equipment working condition, work doing efficiency and system's heating efficiency of compressor have been improved, reach the purpose of low temp compensating, when making machinery equipment be lower than-10 ℃ of work at temperature, efficiency COP value still can reach more than 2.In addition, the structure of this compensator is also very simple, so easy to manufacture, with low cost.

The specific embodiment

As shown in Figure 1, pipe 2 and outer tube 1 in this pipe-type compensator (interior tubular type) comprises, the length of outer tube 1 is less than the length of interior pipe 2; Manage on 2 in outer tube 1 is enclosed within and the outer circumference surface of the inner peripheral surface of outer tube and interior pipe maintenance certain spacing (concrete numerical value can be determined as required voluntarily), be beneficial to the circulation of gas-liquid; After the annular end at the outer tube 1 two ends sealing (but general welded closure), two ends are provided with import 4, outlet 3 respectively again, are outlets 6 at the end corresponding to the import of outer tube on the interior pipe 2, and the other end is import 5.The caliber of outer tube 1, interior pipe 2 and length can be determined according to the capacity plan of the hot equipment of refrigeration.In addition by among the figure as can be known: this heating-cooling equipment is made U-shaped with compensator; Nature also can be made annular and other different shape as required.

Be the utilization of recuperation of heat compensator 12 in the hot device systems of refrigeration as shown in Figure 2: the import 4 of compensator outer tube connects with 7 outlets of off-premises station interchanger, and the outlet 3 of compensator outer tube connects with the air-breathing interface of compressor 8; The import 5 of pipe connects with the port of export of indoor set interchanger 9 in the compensator, and the outlet 6 of pipe links by flow controller 10 and the import of off-premises station interchanger in the compensator.In addition, the arrow among Fig. 1, Fig. 2 is the flow direction of cold-producing medium.

Shown in Figure 3 is refrigeration hot energy efficiency of equipment COP value curve map (wherein abscissa is an environment temperature), and efficiency COP value still can reach more than 2 when-10 ℃ of work, and the raising of compressor work doing efficiency is very tangible.
