Embodiment 1

[0036] Absorption cooling mode of operation.

[0037] Such as figure 1 So, when the solar energy is sufficient, it runs completely according to the absorption refrigeration cycle flow. At this time, the compressor is in a standby state; the refrigerant is heated to the solution in the solar direct generator 1, and the refrigerant evaporates to generate refrigerant vapor. After passing through the gas-liquid separator 2 and the one-way valve 3, after the temperature and pressure are lowered and condensed in the condenser 4, part of the refrigerant liquid is stored in the liquid receiver 5, and the refrigerant enters the evaporator 7 through the throttle valve 6, and the liquid refrigeration The refrigerant absorbs heat and vaporizes in the evaporator, turns into a low-temperature and low-pressure refrigerant vapor, and produces a cooling effect; the low-temperature and low-pressure refrigerant vapor is absorbed by the high-concentration absorbent solution from the absorber 9 th...

Embodiment 2

[0040] Electric compression refrigeration operation mode

[0041] When the solar energy is completely insufficient or at night, the vapor compression refrigeration operation is used; in this way, the continuity of the solar refrigeration system operation is ensured, and the mode is switched by the refrigerant vapor pressure sensor, and the air conditioning refrigeration load can be completely controlled by the electric compression refrigeration cycle process. The first loop is responsible; when the pressure sensor detects that the refrigerant vapor pressure generated in the generator 1 is lower than the minimum threshold, the absorption refrigeration cycle loop is closed, and the electric compression refrigeration operation mode is directly entered.

[0042] The operation process is as follows. When the system detects that the generator cannot provide sufficient condensing pressure, under the action of the automatic control system, the valve F2 and the check valve 3 are closed;...

Embodiment 3

[0044] Absorption-compression composite energy system operation mode

[0045] When the pressure sensor detects that the refrigerant vapor pressure generated in the generator 1 is higher than the minimum generated value, the absorption refrigeration cycle loop is automatically opened, and the absorption-electric compression composite energy system operation mode is entered.

[0046] When the solar energy is insufficient, the valve F3 is opened under the action of the automatic control device, and the refrigerant vapor from the evaporator 7 is divided into two routes through the valve F1, and the refrigerant vapor in one route passes through the valve F3 and is sucked by the compressor 13, and the subsequent process It operates according to the electric compression refrigeration cycle; when the solar energy is completely insufficient or at night, the cooling load of the air conditioner can be completely borne by the compression refrigeration cycle;

[0047] Another way of refrig...

Abstract

The invention relates to a direct-type solar air conditioner. The direct-type solar air conditioner is a direct-type solar air conditioning compound system which comprises a solar direct generator, a condenser, a throttle valve, an evaporator, a compressor, an air-cooling adiabatic absorber, a heat exchanger, a solution heat exchanger, an automatic control device and the like. The direct-type solar air conditioning compound system is characterized by integrating a solar thermal collector and a generator and adopting an air-cooled type absorber.

Description

technical field [0001] The invention belongs to the technical field of air conditioning and refrigeration, and in particular relates to an air conditioning refrigeration and heating technology utilizing solar energy. Background technique [0002] With the improvement of people's living standards, people's requirements for the living environment are getting higher and higher. The air conditioner is already a popular electrical appliance, but the conventional electric compression refrigeration air conditioner consumes a lot of power resources, resulting in having to pull Power cuts have affected the living standards of the entire nation. At present, most of the electric energy used in China is thermal power generation, which further consumes a large amount of coal, thereby producing more carbon dioxide and causing further deterioration of the environment; it is urgent to develop some energy-saving and environmentally friendly air-conditioning and refrigeration technologies , ...
