Abstract
The invention is a kind of water-source heat pump evaporator which is especially suitable for low-temperature water source, it has a transverse pot shell, inlet of secondary refrigerant is set at one end of the shell and outlet of secondary refrigerant is set at the other end of the shell, transverse heat exchange tube is laid out in the shell and both ends of the heat exchange tube connects with pipe sheet of both ends of the shell correspondingly. Refrigeration with jet and liquid-spraying tube mixed with refrigeration oil are set above the transverse heat exchange tube, refrigerant, refrigerant vapour, discharge tube of refrigeration oil are set below pot shell. The invention has a structure of single flow shell and tube evaporator, it is characterized in that secondary refrigerant enters from one end and is discharged from the other end directly through heat exchange tube, refrigerant and refrigeration oil intermixture exchange for heat through heat exchange tube by spraying, flow of secondary refrigerant through evaporator is large and the flow speed is fast, time for exchanging is short, thus, it avoids that evaporator freezes because of low-temperature water source effectively. Moreover, because dosage of refrigerant is little, refrigerant can mix with refrigeration oil sufficiently and it is effectual to return oil.
Description
Technical field
The present invention relates to A/C evaporator, be specifically related to a kind of water source heat pump evaporator that is applicable to low-temperature water source.
Background technology
Water resource heat pump is at present putative efficient, energy conservation air conditioning equipment, needs suitable water source during its operation.Underground water is the good water sources of water resource heat pump, and the extraction but underground water need be dug a well exists such as well water and recharges difficulty, easily causes many problems such as underground water pollution.River, river, lake, seawater are being contained huge low temperature heat energy, but since winter its water temperature about-2 ℃-0 ℃, when adopting present all types of evaporimeters to extract heat in its low water temperature, its evaporimeter easily freezes, and causes heat exchange normally to carry out.In addition, the flooded evaporator of prior art is because the refrigerant amount that fills is big, and is difficult to discharge, particularly freon class cold-producing medium after the refrigeration oil that enters evaporimeter and the refrigerant mixed and after refrigeration oil mixes, refrigeration oil effectively can't be sucked back compressor.Have, existing showering spray type and recirculation type evaporator all are to make cold-producing medium carry out forced circulation in evaporimeter by liquid pump again, and its cost of equipment height connects complicated.
Summary of the invention
The objective of the invention is at the problems referred to above, a kind of water source heat pump evaporator that is applicable to low-temperature water source is provided.
The technical scheme that realizes above-mentioned purpose is: a kind of water source heat pump evaporator that is applicable to low-temperature water source, it has an end and is provided with the refrigerating medium import, the other end is provided with horizontal jar of shape shell body of refrigerating medium outlet, in jar shape shell body, be placed with two ends and be connected to horizontal heat exchanger tube on each respective side shell ends tube sheet respectively, above heat exchanger tube, be provided with cold-producing medium and refrigeration oil mixed liquor shower, be provided with cold-producing medium and refrigerant vapour and refrigeration oil discharge pipe in the bottom of jar shape shell body.
The present invention adopts refrigerating medium is entered by an end, by directly discharging by the other end behind the heat exchanger tube, and the single process shell and tube evaporator structure of utilizing spray to make cold-producing medium and refrigeration oil mixed liquor carry out heat exchange through heat exchanger tube, the flow of its refrigerating medium by evaporimeter is big, flow velocity fast and cold-producing medium between heat exchanger time short, thereby the problem of effectively having avoided evaporimeter to use low-temperature water source easily to freeze, and the oil return effect of evaporimeter is effectively improved.
The present invention also has following advantage:
1, owing to is provided with shower and nozzle, characteristics with showering spray type evaporimeter, and saved the liquid pump of forced circulation, power by electric expansion valve and compressor, on the heat-transfer area of heat exchanger tube, it is well wetting that the heat exchanger tube surface is obtained, thereby improved the heat exchange effect with the liquid refrigerant spray, make system simple, cheap.
2, owing to utilize electric expansion valve, the degree of superheat and mistake liquid measure easily reach high precision in control, realize circulating kind of refrigeration cycle process easily, so the cold-producing medium consumption is considerably less, and have reached the effect of flooded evaporator.
3, because cold-producing medium and refrigeration oil and refrigerant vapour are discharged by the evaporimeter bottom, so overcome flooded evaporator because of the upper end of exhaust outlet at housing, the refrigeration oil that dissolves in the cold-producing medium is the problem of difficulty discharge.
Description of drawings
Accompanying drawing is the water source heat pump evaporator structural representation that originally is applicable to low-temperature water source.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present invention is described.
As accompanying drawing, this evaporimeter has a horizontal jar shape shell body 2, and an end bottom of its jar shape shell body is provided with refrigerating medium import 1, and the top of the other end is provided with refrigerating medium outlet 5.Both ends in jar shape housing are provided with the tube sheet 4 that is used for expanded joint or welding heat exchanger tube respectively, are placed with horizontal heat exchanger tube 6 on tube sheet 4, and each heat exchanger tube is connected into and out of the chamber with the refrigerating medium that is made of housing and tube sheet respectively.In housing, be positioned at heat exchanger tube above be provided with the assembling shower nozzle cold-producing medium and refrigeration oil mixed liquor shower 3, be provided with cold-producing medium, refrigerant vapour and refrigeration oil discharge pipe 7 in the bottom of jar shape shell body.
When the present invention moves, refrigerating medium flows in heat exchanger tube, refrigeration oil and refrigerant mixed liquid from condenser enter shower 3 after the electric expansion valve throttling, through shower nozzle cold-producing medium and refrigeration oil mixed liquor are nebulized injection stream through heat exchanger tube, through with the heat exchanger tube evaporation and heat-exchange after, refrigerant vapour and the aqueous cold-producing medium of evaporation is not together through the gas-liquid separator of discharge pipe 7 to unit fully, the gas after separating is sent into the compressor air suction mouth and is sucked the back compression cycle.Because the cold-producing medium consumption is few, so refrigeration oil and refrigerant mixed are abundant, oil return is effective, and is identical with dry evaporator basically.
The present invention also is fit to other refrigeration plant and does the evaporimeter use.
