Embodiment Construction

[0020] like Figure 1 ~ Figure 3 As shown, the cold storage system with the natural cooling function provided in this embodiment includes a warehouse 1 and a refrigeration unit for the warehouse 1. The refrigeration unit in this embodiment adopts a conventional refrigeration unit in the market, and it is mainly composed of a compressor, a condensing It is composed of four core parts, namely, the device, the expansion valve and the evaporator, forming a relatively mature and widely used refrigeration cycle system. When the outdoor ambient temperature is high, start the compressor, cooperate with the condenser, expansion valve and evaporator to perform cycle refrigeration for the warehouse; when the outdoor ambient temperature is low, especially when it is lower than -10°C, turn on the compressor for refrigeration The energy consumption is large, and the cooling liquid in the condenser can be refrigerated by using the natural ambient temperature outside to ensure that the workin...

Abstract

The invention discloses a cold storage system with a natural cooling function, which includes a storage room and a refrigeration unit composed of a compressor, a condenser, an expansion valve and an evaporator. A hoisting device is installed on the upper side of the outer side of the storage room, and a liquid storage device is suspended on the hoisting device. The upper surface of the condenser housing is provided with a cooling liquid outlet, the lower surface of the condenser housing is provided with a cooling liquid inlet, and the bottom of the liquid storage tank is provided with a liquid outlet. The liquid outlet of the liquid storage tank is connected to the condenser A cold liquid pipe is connected between the cooling liquid inlet of the liquid storage tank, and a liquid inlet is opened on the upper part of the liquid storage tank, and a thermosiphon pipe is connected between the liquid inlet of the liquid storage tank and the cooling liquid outlet of the condenser. Control valves are installed on the siphons. In the outdoor low-temperature environment, the invention can use the thermosiphon effect to condense the heated cooling liquid by adding a liquid storage tank equipped with cooling liquid in the high place of the warehouse, so that natural cooling can be carried out under the premise of stopping the compressor. cycle to cool the warehouse.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a cold storage system with a natural cooling function. Background technique [0002] In recent years, with the rapid growth of the refrigerated and frozen storage industry, the construction of domestic cold chain logistics has entered a peak period, and the demand for cold storage has also increased. At present, there are various refrigeration systems or refrigeration units used in cold storage, but the core components are still composed of compressors, condensers, expansion valves and evaporators. Since the cold storage runs throughout the year, the energy consumption of its units is particularly high, especially the cold storage at 2-8 °C is used most, the compressor is almost always in working condition, and the energy consumption rate is relatively high. In the northern part of my country, the outdoor temperature is low in winter, and the temperature difference between...
