Embodiment approach 1

[0025] Such as figure 1 As shown, it is a schematic structural diagram of the air conditioning and refrigeration system provided in this embodiment, and the direction of the arrow in the figure is the flow direction of the refrigerant. The air conditioning and refrigeration system includes a throttling capillary 1 and a flow control device 2 for adjusting the flow of refrigerant in the air conditioning and refrigeration system. The flow control device 2 is arranged in parallel with the throttling capillary 1 .

[0026] In the refrigeration process of the air conditioner, the throttling capillary 1 is used as the main throttling element. Under normal temperature conditions, the flow control device 2 is closed, and the refrigerant only passes through the throttling capillary 1 in one path. Under high temperature conditions, the amount of refrigerant required in the refrigeration system increases. At this time, the condensing pressure of the air conditioning system will increase...

Embodiment approach 2

[0035] In this embodiment, the flow control device 2 provided by the present application includes an unloading valve or a pressure switch 6 , and an auxiliary capillary 7 arranged in series with the unloading valve or the pressure switch 6 . When a refrigerant passes through the flow control device 2 , the refrigerant first passes through the unloading valve or the pressure switch 6 and then passes through the auxiliary capillary 7 . In this embodiment, except that the specific structure of the flow control device 2 is different from that of the first embodiment, other structures are the same as those of the first embodiment.

[0036] Such as figure 2 As shown, the flow control device 2 includes a pressure switch 6 and an auxiliary capillary 7 arranged in series. The working process of the pressure switch 6 and the auxiliary capillary 7 is: the opening pressure of the pressure switch 6 is P 2 , the pressure at the refrigerant inflow end of the throttle capillary 1 is P 1 ,...

Abstract

The invention relates to the technical field of refrigerating equipment and in particular relates to an air conditioner refrigerating system. The air conditioner refrigerating system comprises a throttling capillary and further a flow control device adjusting cold media flow in the air conditioner refrigerating system. The flow control device and the throttling capillary are arranged side by side. The control device is opened when outer temperature is higher, so cold media can pass through two paths via the throttling capillary and the flow control device; cold media circulation amount can be increased and work efficiency of the air conditioner in high temperature work condition can be improved; and the air conditioner refrigerating system is simply structured with low manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an air-conditioning and refrigeration system. Background technique [0002] The refrigeration system of the air conditioner is mainly composed of four major equipments: a compressor, a condenser, a throttling element, and an evaporator. These equipments are connected in sequence through pipes and pipe accessories to form a closed system. The refrigerant circulates continuously in the air conditioning system through the four processes of compression, condensation, throttling, and evaporation, and then achieves the purpose of refrigeration. [0003] Due to the simple structure and low cost of capillary tubes, many air conditioners usually use capillary tubes as throttling elements, but once the specifications and length of capillary tubes are determined, they cannot be adjusted. Therefore, under high temperature conditions, the amount of refrigerant circulating in ...
