Abstract

The invention discloses a variable frequency air conditioning unit which solves the problem that in the prior art, the control over temperature and humidity precision by an air conditioner is lower. The variable frequency air conditioning unit comprises a compressor, a condenser, an expansion valve and an evaporator which are sequentially connected. The compressor is further connected with the evaporator. A condensing fan is further arranged above the condenser. An evaporating fan is further arranged above the evaporator. The compressor is a variable frequency compressor, the expansion valve is an electronic expansion valve, and a liquid storage tank is arranged between the condenser and the expansion valve. A humidifier and an electric heater are respectively arranged at an air supply outlet of the evaporating fan. A dehumidifying electromagnetic valve is further arranged between the expansion valve and the evaporator. The variable frequency air conditioning unit provided by the invention has the advantages of high precision control and energy-saving and the like, and is suitable for application.

Description

technical field [0001] The invention relates to an inverter air conditioner unit. Background technique [0002] Laboratory inverter air conditioners are relatively high-end equipment in the current market. They are designed for high-precision laboratories. They usually require a stability of ±0.5°C and a humidity of ±2%. This type of inverter air conditioner is designed for solving Designed for high precision requirements. There is a big difference with household inverter air conditioners, household inverter air conditioners mainly start from the energy saving aspect, and promote the concept of energy saving. [0003] In order to maintain the indoor constant temperature and humidity requirements, the conventional constant temperature and humidity air conditioners usually implement measures such as starting and stopping the compressor, changing the capacity of the heater and humidifier, and changing the speed of the indoor fan. Although the conventional constant temperatur...
