Problems solved by technology
[0003] At present, there are mainly frequency conversion regulation technology, multi-machine parallel variable capacity technology, and liquid refrigerant storage variable capacity technology in terms of variable capacity adjustment at home and abroad. The latter two methods are not suitable for promotion in refrigeration and air conditioning test equipment due to poor control accuracy. Frequency conversion regulation Although the technical control precision is high, its cost is high, the control is more complicated, and it is not conducive to large-scale promotion. Therefore, this paper develops a compression condensing system, which can realize the stepless adjustment of the cooling capacity from zero to full load

Embodiment Construction
[0024]The present invention will be specifically described below in conjunction with specific embodiments.
[0025]The compression condensing system of the present invention is mainly divided into four parts: compression condensing part, system adaptive part, variable volume adjustment part, measurement control part;
[0026]Compression and condensation part: This part is mainly composed of compressor 1, condenser 2, oil 4, and gas-liquid separator 13. What enters the compressor is a low-temperature and low-pressure gaseous refrigerant. The compressor compresses it into a high-temperature and high-pressure gaseous refrigerant and discharges it into the condenser. The condenser is water-cooled. The condenser fully cools the high-temperature and high-pressure gaseous refrigerant, and the heat is cooled The water is taken away, and the refrigerant becomes a high-pressure liquid refrigerant after passing through the condenser.
[0027]System adaptive part: This part is mainly composed of suction...

Description
Technical field[0001]The invention belongs to the field of compression condensation systems, and in particular relates to a compression condensation system with stepless adjustment of refrigeration capacity.Background technique[0002]Traditional refrigeration and air-conditioning product performance test devices usually use fixed-capacity compressors, and then use adjustable-capacity electric heating to hedge the cooling capacity in order to achieve a constant temperature between the test environments. This approach will inevitably result in a waste of energy due to the use of electric heating to offset the refrigeration capacity of the compressor. In order to solve this problem, the best way is to realize that the cooling load and heat load required by the environment can be individually steplessly adjusted. When the environment is a cooling load, only electric heating is needed. The balance of the system can be solved only by using the power regulator to drive the electric heating....
