Water-cooled heating and cooling constant temperature unit

Water Cooling and Heating Constant Temperature Unit

Introduction

Water Constant Temperature—Water Cooling and Heating Constant Temperature Unit. The heating method utilizes heat from the air to warm the water, eliminating the need for additional heating elements. In this era of environmental conservation and energy efficiency, this unit fully meets market demands..

Cooling Principle of the Unit

The compressor operates, converting low-temperature, low-pressure gaseous refrigerant into high-temperature, high-pressure gaseous refrigerant, which enters the condenser. Part of the heat from the refrigerant inside the condenser is expelled by external cooling water or cooling fans. After releasing heat, the refrigerant liquefies into a high-temperature, high-pressure liquid and flows out. It then passes through a dryer filter for drying and filtration before entering the expansion valve for throttling (a rapid cooling process) and pressure reduction. The refrigerant liquefies into a low-temperature, low-pressure liquid and enters the evaporator for heat exchange. The low-temperature, low-pressure liquid refrigerant absorbs heat from the surrounding medium (water, oil) outside the evaporator. During the heat absorption process, the refrigerant temperature remains unchanged while its volume changes. After absorbing heat, the low-pressure hydraulic refrigerant vaporizes into a low-temperature, low-pressure gaseous refrigerant and enters the compressor. It is compressed into a high-temperature, high-pressure gas and enters the condenser, thereby completing the entire refrigeration cycle.

Heating Principle of the Unit

Based on the refrigeration principle, the compressor operates, converting low-temperature, low-pressure gaseous refrigerant into high-temperature, high-pressure gas, which passes through a four-way valve and a liquid storage tank. The refrigerant enters the condenser, where the heat is utilized to heat the water tank, raising the water temperature to as high as 90 degrees. After releasing heat, the refrigerant liquefies into a high-temperature, high-pressure liquid and flows out. It then passes through a dryer filter for drying and filtration before entering the expansion valve for throttling (a rapid cooling process) and pressure reduction. The refrigerant liquefies into a low-temperature, low-pressure liquid and enters the evaporator for heat exchange. The low-temperature, low-pressure liquid refrigerant absorbs heat from the surrounding medium (water, oil) outside the evaporator. During the heat absorption process, the refrigerant temperature remains unchanged while its volume changes. After absorbing heat, the low-pressure hydraulic refrigerant vaporizes into a low-temperature, low-pressure gaseous refrigerant and enters the compressor. It is compressed into a high-temperature, high-pressure gas and enters the condenser, thereby completing the entire heating cycle.
