Abstract

The improved household refrigerator features that a stored liquid heat exchanger which is composed of liquid storage device and a capillary tube or transition assembly between capillary tube and evaporator is installed between the final-stage evaporator and return tube or before the return tube if evaporator is parallelly connected. The heat exchange between the stored liquid heat exchanger and refrigerating chamber is reduced as possible. It has more functions of gas-liquid separation, liquid storage and heat return.

Description

Liquid storage-the heat regenerating method of refrigerator and device thereof

The present invention relates to the improvement of family expenses refrigerating appliance, especially energy-conservation and raising adaptability for energy.

Existing refrigerating appliance, generally adopted the capillary regenerator already, it is evaporimeter stream to be returned carry out heat exchange between the muffler of compressor and the throttle capillary tube behind the condenser with so that high-pressure refrigerant is cold excessively, and to improve refrigerating capacity, this device increases system's refrigerating capacity 5-8% approximately.

In equipment component, can produce the wet stroke problem of compressor during for the incomplete evaporation of solution cold-producing medium, reservoir has been installed; it is indoor between generally placing; its interior storage refrigerant liquid slowly evaporates during shutdown, has also slowed down the rise of this indoor temperature, and energy-saving effect is arranged.

Yet for the variation of environment temperature in adapting in a big way and the variation of service condition, existing refrigerator, the ice box product, comprise that the product that uses above-mentioned two kinds of devices all is difficult to bear, especially for the product high-grade, that adjustability is strong, existing flow process is difficult to adapt to, because the existence of existing reservoir, possibility is chamber cooling between this device of placement constantly, thereby makes this room temperature degree be difficult to accurately regulate and can not heighten warm area, more can't close.And regenerator also can only be in operation process, reclaim compressor return air sensible heat (latent heat that also has the part drop sometimes) therefore above-mentioned device all can't meet the demands.

The objective of the invention is to design a device, make refrigeration system adapt to the external environment condition that changes in both can be in a big way, and the different requirements of inner each chamber cold, again can saves energy, add the startup process of block system.

Method of work of the present invention is: (1) not between level evaporimeter and the muffler (then being before muffler) as the evaporimeter parallel connection install the liquid storage heat exchanger additional.(2) the liquid storage heat exchanger is to be formed by the transition combination between reservoir and one section capillary or capillary and the evaporimeter, realizes good heat exchange between them.(3) this liquid storage heat exchanger as far as possible and the refrigeration between the chamber reduce heat exchange.

The present invention can play gas-liquid separation liquid storage and the multiple function of backheat, the temperature that conforms variation in a big way, also can adapt to the variation of the service conditions such as change of load, utilization in especially adjustable, the strong refrigerator of control function, typical as use the product of the cold coalignment patent of multi-door refrigerator at cooling process.

The invention will be further described below by way of embodiments and drawings:

Figure 1A, 1B are respectively the structure chart that capillary is immersed in liquid storage regenerator bottom and is wrapped in the liquid storage regenerator outward, and Figure 1B has shown the embodiment of reservoir container and the tight heat exchange contact of capillary 8 metal tubes.

Fig. 2 be one three temperature range (as three compartment refrigerators) but temperature independent regulation separately, even the refrigerator flow chart that can stop using.

Reservoir 1 volume (common three-door refrigerator) is 50ml among the figure, can store up the about 72g of R12, it is enough to satisfy the requirement that each room temperature degree is adjusted in nearly all operating mode scope, even under the situation that the first, the second chamber evaporimeter 2,3 stopped using, the wet stroke phenomenon of compressor can not take place yet, obviously, when starting shooting once more, in the reservoir liquid to throttling after the fluid of (or in throttling) fully cross cold or cooling, accelerated toggle speed greatly, V ₁, V ₂Be the magnetic valve of evaporimeter 2,3 work in chamber between control, 4 is another chamber evaporimeter, and regenerator 5 uses as usual, and Qk is a condenser, and W is a compressor.Reservoir is cylindricality copper (aluminium) pipe closing in dumbbell shaped diplopore, for connecing evaporator tube 9 and product heat cal rod 10, in when soaking capillary 8, capillary is drawn from the reservoir bottom, and sealing is lived outlet, reservoir places the heat insulation layer of refrigerator etc., considers that volume is bigger, can be made into the less volume that accounts for of flat post or square column.
