Constant-temperature heating and constant-humidity humidifying device

Abstract

The invention relates to a constant-temperature heating and constant-humidity humidifying device comprising: a refrigeration cycle system, a heating cycle system, an internal cycle system, an external cycle system, a water tank, and a control unit. The refrigeration cycle system comprises a refrigeration compressor, a first condenser, a first expansion valve, and a first evaporator; the heating cycle system comprises a heat pump compressor, a second condenser, a second expansion valve, and a second evaporator; the internal circulation system communicates with the control space via a duct and includes an internal circulation humidifier, a first evaporator and a second condenser; the external cycle system communicates with the external environment via a duct and includes an external circulation humidifier, a second evaporator and the first condenser; the water tank communicates with the first evaporator, the second evaporator, the internal circulation humidifier, and the external circulation humidifier; the control unit controls the operation of the refrigeration compressor, the heat pump compressor, the internal circulation humidifier, and the external circulation humidifier. As a result, the constant-temperature heating and constant-humidity humidifying device is possible to adjust different temperature and humidity of the control space and to avoid adding water to the water tank.

Description

technical field [0001] The invention relates to a constant temperature and humidity machine, in particular to a constant temperature and humidity machine for controlling the temperature and humidity of a sealed space where cultural relics or antiques are stored. Background technique [0002] As conventional constant temperature and humidity machines, there are the following four types. [0003] Air-conditioning type: a system composed of a compressor, a four-way valve, an evaporator, a condenser and a humidifier; the four-way valve is used to switch the evaporator and the condenser to provide cooling or heat for the regulated space, and the evaporator is used to reduce the regulated temperature. The humidity of the space, through the humidifier to increase the humidity of the regulated space. [0004] Auxiliary heating type: a system composed of a compressor, a solenoid valve, an evaporator, a condenser, a second condenser and a humidifier; Cooling capacity, the second con...

AI Technical Summary

Problems solved by technology

[0007] However, in the air-conditioning constant temperature and humidity machine, it is impossible to heat up and dehumidify the regulated space, and it needs frequent maintenance of adding and draining

[0008] In addition, in the auxiliary heating type constant temperature and humidity machine, the heat provided by the second condenser is limited, and it is also impossible to heat up and dehumidify the regulated space, and it needs frequent maintenance of adding and draining

[0009] In addition, in the constant temperature and humidity machine of the heat pump compressor type, it is not possible to heat up and dehumidify, cool down and dehumidify the controlled space, and it is necessary to add water frequently for maintenance

[0010] In addition, in the electric heating type constant temperature and humidity machine, the electric heating efficiency is low and there is a fire hazard, and frequent maintenance of filling and draining is required
