Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 As shown, the wide-temperature fresh air stepless adjustment refrigeration device consists of a first-stage refrigeration system 10, a first-stage electric heater 1, a second-stage refrigeration system 20, a second-stage electric heater 2, and a third-stage refrigeration system 30. 1. The third-stage electric heater 3 is composed of a thyristor-controlled electric heater for heating. The first-stage electric heater 1 is placed behind the evaporator 16 of the first-stage refrigeration system 10, and the second-stage evaporator 26 is placed behind the first-stage evaporator 26. After the first-stage electric heater 1, the second-stage electric heater 2 is placed behind the second-stage evaporator 26, the third-stage evaporator 36 is placed behind the second-stage electric heater 2, and the third-stage electric heater 3 is placed A...

Abstract

The invention discloses a wide-range-temperature full-fresh air stepless regulation type refrigeration plant, which comprises three stages of refrigeration systems respectively provided with an evaporator, the evaporators of the three stages of refrigeration systems are arranged in an air duct, an electric heater is arranged in the air duct behind each stage of evaporator, the wide-range-temperature full-fresh air stepless regulation refrigeration plant further comprises a controller, and the controller is respectively electrically connected to each refrigeration system and each electric heater. According to the invention, wide-range-temperature full-fresh air stepless regulation can be realized, realizing wide-range-temperature refrigeration operation, the three stages of refrigeration can be selectively switched on under the condition that the working condition is not harsh, and the wide-range-temperature full-fresh air stepless regulation type refrigeration plant has the advantagesof simple structure, convenience in use, convenience in maintenance and high reliability.

Description

technical field [0001] The invention relates to the field of air conditioning devices, in particular to a wide-temperature fresh air stepless regulation refrigeration device. Background technique [0002] The air conditioning in the environment of special equipment requires a large amount of air supply, stepless adjustment for cooling, multi-level adjustment for heating, fresh air for return air, and a wide range of ambient temperature (-45°C-55°C). , the air supply temperature requirement is low, and the dehumidification requirement is reliable and strict. Under high temperature conditions (such as the ambient temperature of 55°C), the supply air temperature is also required to be low, and the extreme value of the temperature difference between the supply and return air is large, which is difficult to directly achieve with single-stage cooling. [0003] At present, the adjustment of cooling capacity usually includes unloading, electric heat balance, and frequency conversio...
