  There are various types of water heaters, and   heat pump water heaters   are one of them, so how do you install a heat pump water heater?  The following   heat pump water heater supplier  will tell you how to install a heat pump water heater. 1. Positioning of the unit About the positioning of the unit, first of all, we must determine the placement of the unit, mainly considering the load-bearing of the floor, the impact of the inlet and outlet air of the unit, in houses with natural gas, oil or wood stove, the heat pump coil should be installed on the warm side (downstream) of the furnace. If a heat pump is added to an electric furnace, the heat pump coil can usually be placed on the cold side (upstream) of the furnace for maximum efficiency. 2. Foundation fabrication Cement or channel steel can be used. The foundation must be on a load bearing beam of the floor to avoid the floor collapsing and causing injury or death because it is not on a load bearing beam. To prevent snow from

  The   chiller refrigeration system   consists of four basic parts, namely compressor, condenser, throttle and evaporator. The four major parts are connected by copper pipes in a certain order to form a closed system, and the system is charged with a certain amount of refrigerant. The role of industrial chillers is mainly to provide chilled water to various industries to cool down the equipment, to improve the accuracy of the product, improve the role of production efficiency. After the user has purchased and installed the industrial chiller, it is time to observe its actual operation. So what are the operating parameters of the industrial chiller? Its operating parameters are mainly voltage, current, power, temperature, pressure, flow rate, liquid level, concentration, etc. Voltage: The supply voltage must be in line with the equipment voltage, too high or too low will affect the safe operation of the chiller. Current: There are industrial chillers nameplate current and the actual op

  Screw chiller principle Screw chillers  are named screw chillers because the key component - the compressor is a screw type, the unit is made from the evaporator out of the state of the gas refrigerant; by the compressor after adiabatic compression, into a high temperature and high-pressure state. The compressed gas refrigerant, in the condenser, isobaric cooling condensation, after condensation changes into liquid refrigerant, and then through the throttle valve expansion to low pressure, into a gas-liquid mixture. The liquid refrigerant in low temperature and low pressure, in the evaporator, absorbs the heat of the cooled material and becomes gaseous refrigerant again. The gaseous refrigerant re-enters the compressor through the pipeline and starts a new cycle. These are the four processes of the refrigeration cycle, which is also the main working principle of the screw chiller. Flooded Type Screw Type Chiller The  flooded type screw type chiller  adopts efficient semi-closed screw
