Abstract

A kind of refrigerator with high efficiency and low cost consists of rotating casing, condensator with great rotating radius, evaporator with small rotating radius, etc. The present invention features no-rotating inner stator staying in rest by the gravitational attraction inside the rotating casing, the pumping effect between the rotating casing and the inner stator to circulate refrigerant between the condensator and the evaporator, the compressing heat liberation of the refrigerant owing to the effect of powerful centrifugal force and pumping force, and the expansion heat liberation of the refrigerant in the evaporator with relatively centrifugal force. The present invention features the integral refrigerator, only one common motor used, no need of capillary and other throttle unit for high efficiency, and unique dehumidification effect. The present invention may be used in air conditioner with low cost.

Description

Air-conditioning refrigeration plant

1, technical field:

The present invention relates to a kind of heat pump that utilizes the compression of fluid refrigerant and the generation of expanding to heat and freeze.

2, background technology:

At present employed heat pumps such as air-conditioning, freezer have been mature technique very, and its principle is to utilize the compressed machine pressurization of gas coolant to become the liquid heat release mostly, freezes through the throttling arrangement reduction vaporization after the heat radiation again.

3, summary of the invention:

The condenser and the rotary shell of the evaporimeter of little radius of turn and big radius of turn are made an integral body, rotate with rotary shell, are placed with in the rotary shell and depend on terrestrial gravitation to keep non-rotary inner stator.Rotary shell and inner stator interact, and utilize modes such as centrifugation or the work of drive mechanical compressor to produce the pump action firmly, and refrigerant is circulated between evaporimeter and condenser.When refrigerant is flowed through the condenser of big rotation half warp, be subjected to strong centrifugal force and pump action heat release simultaneously, when refrigerant is flowed through the evaporimeter of little rotation half warp, be subjected to more weak centrifugal force and swelling heat absorption with force compresses.

Advantage of the present invention is: 1) whole refrigerating plant is made one, most of thin aluminum sheet even sheet iron stamping parts of adopting, and cost is low and refrigerant is difficult leaks; 2) only can freeze with a common motor and can efficiently radiates heat and impel the cold wind circulation, motor cost is low; 3) can be without throttling devices such as capillaries, the refrigerating efficiency height.4) even in order to improve power mechanical compressor is installed in inner stator, its load that bears is also very little, and friction loss is little; 5) rotation of evaporimeter easily is thrown to condensed water on the cold wind kuppe outside the discharge machine, and the incomparable effect on moisture extraction of other type is arranged.6) the introduction outdoor air is also very convenient.

4, description of drawings:

Fig. 1 is that this refrigerating plant prolongs among Fig. 2 the profile of D-D direction in the C-C direction and Fig. 3, wherein primary structure is a condenser 2), pipe-coil type evaporator 3), rotary shell 5), inner stator 6) etc., wherein the single line arrow is represented the flow direction of refrigerant, and double-lined arrow is represented the flow direction of room air.

Fig. 2 is the profile that prolongs A-A direction among Fig. 1, mainly is condenser 2) structure, for the ease of explaining, it is less that its ratio is drawn.

Fig. 3 is the profile that prolongs B-B direction among Fig. 1, mainly is rotary shell 5) and inner stator 6) structure.

5, concrete embodiment:

Be provided with for the ease of manufacturing and be fixed in rotary shell 5) hollow shaft 1), the one end is installed on the power input devices such as motor, the other end is provided with the Luo plug joint 4 of being convenient to fill refrigerant), when power input device drives hollow shaft 1) during rotation, rotary shell 5), the condenser 2 of big radius of turn) and the evaporimeter 3 of little radius of turn) rotate together.Inner stator 6) by hollow shaft 1) the last bearing 8 of being with sealing device) support, inner stator 6) there is eccentrically mounted weight 7 inside), because terrestrial gravitation is to eccentrically mounted weight 7) effect, can keep inner stator 6) not with rotary shell 5) rotation, so inner stator 6) Nei Bu refrigerant does not bear centrifugal force, its inside pressure everywhere equals the pressure at place, axle center.Rotary shell 5) Nei refrigerant is because of being subjected to action of centrifugal force, and its pressure is greater than the pressure at place, axle center, also just greater than inner stator 6) inner pressure, refrigerant is by air inlet 15) enter inner stator 6), increased inner stator 6) pressure of inside.By inner stator 6) cavity is through hollow shaft 1) enter condenser air inlet pipe 13) and refrigerant, be subjected to action of centrifugal force once more.So an inner stator 1) just constituted two stage centrifugal pump.

As shown in Figure 2, when refrigerant enters condenser air inlet pipe 13) time compression heat release, from condenser return duct 10) flow to evaporimeter 3) time just swelling heat absorption, so air inlet pipe 13) Nei temperature is higher than return duct 10) in temperature, so air inlet pipe 13) in refrigerant than return duct 10) in refrigerant density little.The poised state of this moment is, air inlet pipe 13) Nei liquefaction face 12) near from the axle center, return duct 10) Nei evaporating face 11) far away from the axle center, have only with the pump action and firmly make evaporating face 11) vaporize to the close refrigerant that just can make in axle center, this is the main circulation resistance of refrigerant, and the resistance size depends on air inlet pipe 13) and return duct 10) between the temperature difference.So this refrigerating plant can not use throttling devices such as capillary.

In addition, be non-rotary cold wind kuppe 9 among Fig. 1); Place in the needs insulation is provided with insulation material 14); Return duct 10) inwall should adopt insulation material; Slow-speed of revolution type still needs throttling arrangement; Condenser 2 in the example) in refrigerant flow to and condenser 2) rotation in the same way; Evaporimeter 3) the stamped aluminium lamination radiator similar condenser 2 of employing), cost is lower.
