< basic principle of operation of air conditioner >

The air conditioner performs a refrigerating cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and refrigerating or heating an indoor space.

The low-temperature low-pressure refrigerant enters the compressor, the compressor compresses the refrigerant gas into a high-temperature high-pressure state, and the compressed refrigerant gas is discharged. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state formed by condensation in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner may adjust the temperature of the indoor space throughout the cycle.

An outdoor unit of an air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, an indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater of a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler of a cooling mode.

Referring to fig. 1 to 12, the present application relates to an air-cooled energy storage refrigeration apparatus 1000 for providing cold energy to an energy storage tank (e.g., a container), wherein the air-cooled energy storage refrigeration apparatus 1000 generates cold energy using the cooling operation principle of the air conditioner as above and introduces the cold energy into, for example, the container.

The air-cooled energy storage refrigeration device 1000 includes a vertical frame 1100, a plurality of mounting plates 1200, and a refrigeration cycle system 1300.

Among them, the refrigeration cycle 1300 includes a compressor unit 1350, a condenser 1330, and an evaporator 1310/1310', and the refrigeration apparatus mainly uses the refrigeration cycle 1300 to perform refrigeration, and the installation positions of the compressor unit 1350, the condenser 1330, and the evaporator 1310/1310' are described below.

The vertical frame 1100 is the structure of the whole air-cooled energy-storage refrigeration device 1000, and its stability can determine the stability of the whole refrigeration device 100.

A plurality of mounting plates 1200 are mounted on the upright frame 1100 to form an overall integrated exterior structure of the refrigeration appliance 1000.

Referring to fig. 1 to 6, a mounting plate is mounted to the vertical frame 1100 such that the vertical frame 1100 is divided into an upper evaporation zone, a lower condensation zone, and a lower compressor mounting position located at one side of the lower condensation zone, the lower compressor mounting position being used to mount the compressor unit 1350.

Since the condenser 1330 and the compressor unit 1350 are heavy, their placement in the lower portion may ensure the stability of the entire refrigeration apparatus 1000.

The upper evaporation zone is defined by the top mounting plate 1220, the middle mounting plate 1230 and the circumferential mounting plate 1210, wherein the middle mounting plate 1230 divides the vertical frame 1100 into upper and lower parts, and the lower condensation zone is defined by the bottom mounting plate, the middle mounting plate 1230 and the circumferential mounting plate 1240.

In some embodiments of the present application, referring to fig. 5 to 8, an evaporator 1310/1310', an evaporation fan 1320/1320', and an electronic control box 1600 are disposed in the upper evaporation zone.

Referring to fig. 5, 7 and 8, a condenser 1330 and a condensing fan (one of which is labeled 1340) are disposed in the lower condensing zone, wherein the condenser 1330 forms a side surface of the lower condensing zone (referring to fig. 5 and 8), so that the air inlet surface of the condenser 1330 is completely exposed to the external environment, and the heat exchange area with the external return air flow is increased.

The upper evaporation zone is provided with a plurality of evaporation fans and a plurality of evaporators arranged in parallel, and in some embodiments of the application, the number of the evaporation fans and the number of the evaporators are not necessarily the same, as long as the evaporation fans can lead out cold air flow after heat exchange of the evaporators.

In some embodiments of the present application, a plurality of evaporation fans may be disposed corresponding to a plurality of evaporators, that is, one evaporation fan corresponds to one evaporator, so that each evaporation fan is mainly responsible for delivering the cold air flow after heat exchange by the corresponding evaporator, so as to ensure that the cold energy of each outlet air side of the evaporation fan is as consistent as possible.

In some embodiments of the present application, referring to FIGS. 3 and 5, two evaporators 1310/1310 'and two evaporation fans 1320/1320' are provided.

One evaporation fan 1320 (1320 ') corresponds to one evaporator 1310 (1310 '), so that each evaporation fan 1320 (1320 ') is mainly responsible for sending out cold air flow after heat exchange of the corresponding evaporator 1310 (1310 '), and ensures that the cold energy of each air outlet side of the evaporation fan 1320 (1320 ') is as consistent as possible.

In some embodiments herein, a plurality of inner return air openings 1211 and a plurality of inner air outlets 1212 are provided on the same side front mounting plate 1213 of the upper evaporation zone.

The inner return air inlet 1211 is used to return air flow inside the energy storage housing and the inner outlet 1212 is used to introduce the cold air flow heat exchanged by the evaporator 1310 (1310') into the interior of the energy storage housing.

The plurality of inner return air inlets 1211 and the plurality of inner air outlets 1212 are disposed on the front side mounting plate 1213 and arranged up and down, for example, the plurality of inner return air inlets 1211 are arranged side by side on the lower side of the front side mounting plate 1213 and the plurality of inner air outlets 1212 are arranged side by side on the upper side of the front side mounting plate 1213, see fig. 3.

The number of the plurality of inner return air inlets 1211 and the number of the plurality of inner outlet air inlets 1212 are not necessarily the same, as long as the evaporator 1310 (1310') is capable of returning air flow through the inner return air inlets 1211 and respectively drawing cool air flow through each of the inner outlet air inlets 1212.

As such, the air intake side of the evaporator 1310/1310 'communicates with at least one inner return air inlet 1211, the air outlet side of the at least one evaporator 1310/1310' communicates with the air intake side of the at least one evaporator fan 1320/1320', and the at least one inner air outlet 1212 communicates with the air outlet side of the at least one evaporator fan 1320/1320'.

Each inner air outlet 1212 may be in communication with an air supply duct of the energy storage housing for providing a path of cold air flow to the energy storage housing through each inner air outlet 1212.

In some embodiments of the present application, referring to fig. 3, 5 and 8, to improve the utilization of the evaporators 1310/1310', each evaporator 1310 (1310 ') corresponds to one inner return air inlet 1211, one evaporation fan 1320 (1320 ') and one inner outlet 1212, that is, the air inlet side of the evaporator 1310 (1310 ') faces the inner return air inlet 1211, the air outlet side of the evaporation fan 1320 (1320 ') faces the inner outlet 1212, and the evaporation fan 1320 (1320 ') is located in the air outlet duct between the air outlet side of the evaporator 1310 (1310 ') and the inner outlet 1212.

After the air flow returned through the corresponding inner return air inlet 1211 is subjected to heat exchange through the corresponding evaporator 1310 (1310 '), the cooled air flow after heat exchange is led out from the corresponding inner air outlet 1212 under the action of the corresponding evaporation fan 1320 (1320'), and the air flow is shown by a solid arrow in fig. 8.

Thus, since the inner return air inlet 1211 and the air inlet side of the evaporator 1310/1310 'are opposite, the return air can be introduced in a large area, heat exchange is performed in a large area through the corresponding evaporator 1310/1310', and the cooling capacity after most heat exchange can be led out through the corresponding inner air outlet 1212 after the heat exchange is opposite to the outlet through the inner air outlet 1212.

And when the multiple inner return air inlets 1211 introduce the return air in the same area, the cold energy sent out by the multiple inner air outlets 1212 is basically the same, so as to ensure that the cold energy of the multiple cold storage areas is uniform.

To achieve efficient use of the evaporators 1310/1310', at least one of the evaporators 1310/1310' is arranged diagonally in the upper evaporation zone, and in some embodiments herein, see fig. 5, 6 and 8, the plurality of evaporators 1310/1310' are each arranged diagonally in the upper evaporation zone.

The evaporator 1310/1310' is obliquely disposed with one end against the intermediate mounting plate 1230 and the other end obliquely toward the inner return air opening 1211, see FIG. 6.

In some embodiments herein, to avoid overflow of condensed water on the evaporator 1310/1310' during refrigeration, referring to fig. 6, a water receiving tray 1800 is disposed below the evaporator 1310/1310', i.e., the water receiving tray 1800 is located on the intermediate mounting plate 1230 such that one end of the evaporator 1310/1310' abuts against the inside of the water receiving tray 1800.

Also, a support portion 1700 is provided on the inner side of the front mounting plate 1213 provided with the inner air outlet 1211 and the inner return air inlet 1212, and the support portion 1700 supports the other end of the evaporator 1310/1310'.

Referring to fig. 6, the support 1700 includes a fixed first support plate mounted on the inner side of the front mounting plate 1213 and a second support plate butted against the first support plate and extending away from the first support plate at an obtuse angle, so that the other end of the evaporator 1310/1310 'is abutted against the second support plate to support the evaporator 1310/1310'.

Referring to fig. 5, 7, 8 and 10, an electronic control box 1600 is further provided in the upper evaporation zone, and the electronic control box 1600 is built with the electrical components for the refrigeration equipment.

In order to prevent the electric components from generating heat to the electric control box 1600 when the refrigeration apparatus 1000 is in operation, the electric control box 1600 is disposed on the air outlet side of the evaporator 1310/1310 '(see fig. 8), so that the air flow cools the evaporator 1310/1310' after heat exchange.

In some embodiments of the present application, the electronic control box 1600 is hung on the rear mounting plate 1214 opposite to the front mounting plate 1213 provided with the inner air outlet 1211 and the inner air return 1212 in the upper evaporation zone, which facilitates external maintenance.

When the electronic control box 1600 is large in size and does not meet the installation requirement in space, the electronic control box 1600 can be split into a plurality of small electronic control boxes 1600 (see fig. 5 and 7), but all need to be placed on the air outlet side of the evaporator 1310/1310'.

In some embodiments of the present application, referring to fig. 8 and 10, a heat sink 1900 is further provided on the electronic control box 1600 for ensuring heat dissipation of the electronic control box 1600.

The heat sink 1900 is also disposed on the air outlet side of the evaporator 1310/1310', improving the heat dissipation efficiency of the electronic control box 1600.

In some embodiments of the present application, referring to fig. 5 and 8, the evaporating fans 1320/1320' are located above the corresponding evaporators 1310/1310', and the evaporating fans 1320/1320' employ centrifugal fans to achieve lower return air and upper outlet air (referring to fig. 8) of the upper evaporation zone, avoiding a return air short circuit.

Referring to fig. 5, 10 and 11, the evaporator fan 1320/1320' is mounted using a fan mounting plate 1250 located above the evaporator 1310/1310', and a centrifugal fan directs the cool air flow from the air outlet side of the evaporator 1310/1310' into and centrifugally out of the inner air outlet 1212.

Referring to fig. 5, 7, 8 and 10, the lower condensing zone is provided with a condenser 1330 and a plurality of condensing fans 1340, and the condensing fans 1340 are located at the air outlet side of the condenser 1330.

The condenser 1330 is designed in a plate shape and is one side of the lower condensing zone, i.e., one side of the condenser 1330 is exposed to the external environment, thus increasing the area between the condenser 1330 and the outside return air and improving the refrigerating capacity of the refrigerating apparatus.

The outer return air zone, which communicates with the air intake side of the condenser 1330, is on the same side as the inner return air inlet 1211, and an outer return air inlet 1242 is formed on a rear mounting plate 1241 (see fig. 2) opposite the outer return air zone, which forms the lower condensation zone.

In some embodiments of the present application, the plurality of condensing fans 1340 are mounted within the lower condensing zone by fan mounting brackets 1360.

For example, referring to fig. 2 and 5, the plurality of condensing fans are four condensing fans 1340, and correspondingly, the outlet 1241 is provided with four condensing fans 1340, which respectively correspond to the outlet sides of the four condensing fans 1340.

The four condensing fans 1340 are arranged in two rows and two columns, two of which are each mounted on one fan mount 1360.

In some embodiments of the present application, the condensing fan 1340 adopts a combination of an ac motor and an axial flow fan, which has a large air volume and low cost, and implements a large air volume heat exchange cycle.

In some embodiments herein, referring to fig. 3, 7 and 10, a compressor mounting location is provided on one side of the lower condensing zone, which mounting location provides a compressor unit 1350 that facilitates connection of evaporator 1310/1310' and condenser 1330 piping.

In some embodiments herein, the refrigeration apparatus implements compound refrigeration based on a pump technology, the compound refrigeration mode including a compressor refrigeration cycle mode and an air pump refrigeration cycle mode.

In some embodiments of the present application, the compressor unit 1350 as described above may include a compressor and a gas pump, i.e., the compressor unit 1350 takes the form of a compressor and gas pump combination arrangement.

In some embodiments of the present application, in the compressor unit 1350, the compressor and the air pump are integrally provided in a parallel arrangement, in which case the compressor and the air pump form a compressor-integrated device.

The compressor integrated equipment has two working modes of a compressor and a gas pump.

In the case where the refrigeration apparatus 1000 needs to start the refrigeration mode and operate, the compressor unit 1350 is controlled to start.

After a period of time following start-up of the compressor unit 1350 operation, the outside outdoor temperature is collected.

A control unit (not shown) in the refrigeration apparatus 1000 determines an operation mode of the refrigeration cycle 1300 according to an outdoor temperature to control the refrigeration cycle 1300 to switch between a compressor operation mode (i.e., a press cycle refrigeration mode) and an air pump operation mode (i.e., an air pump cycle refrigeration mode).

The compressor operation mode supports low-frequency low-compression-ratio operation, when the outdoor temperature is higher, the compressor unit 1350 works in the compressor operation mode, full-power operation is used for refrigeration, when the outdoor temperature is lower, the air pump operation mode is adopted, and the energy exchange is realized by utilizing an external natural cold source, so that the energy consumption of the system is reduced.

The integrated equipment with the functions of the air pump and the compressor can reduce the energy consumption by utilizing the natural cold source and greatly reduce the equipment cost.

The air pump air conditioning unit can greatly improve the energy efficiency of the unit at low temperature and in excessive seasons, and reduces the energy consumption.

In some embodiments of the present application, the switching of the compressor refrigeration cycle mode and the air pump refrigeration cycle mode may be controlled according to an outdoor ambient temperature.

When the outdoor ambient temperature is low and the refrigeration cycle system 1300 is switched to the air pump refrigeration cycle mode, if the compressor unit 1350 is a rotation speed controllable compressor, the compressor unit 1350 is in a low frequency operation state, and the outdoor natural cold source is utilized to greatly reduce the operation energy consumption.

When the outdoor environment temperature is higher, the refrigeration cycle system 1300 is switched from the air pump refrigeration cycle mode to the compressor refrigeration cycle mode, the compressor unit 1350 mechanically refrigerates, and refrigeration is realized by directly evaporating the refrigerant in the evaporator 1310/1310', so that a high-efficiency refrigeration effect is achieved.
