R32 Full DC Inverter Heat Pump 20kw Air to Water Heating Pump

What is air source heat pump?Air source heat pump is a device that transfers a large amount of heat contained in the air to the space requiring heat by consuming a small part of electric energy.It can provide users with hot water, refrigeration and heating needs. It has large water volume, high water pressure and constant temperature all day. Compared with coal-fired, oil-fired and gas-fired boilers, air source heat pump can help save more than 40% of energy.Characteristic1. The unit uses air as the heat source for refrigeration, heating and high-temperature hot water. Its efficiency is up to 300-500%.2. Water and electricity are isolated without any pollution discharge. It is environmentally friendly, reliable, energy-saving, reliable and convenient.3. The unit works around the clock with large water production. It can realize centralized water supply.4. The system is more reliable and efficient by adopting the method of circulating heating.5. Refrigeration, heating, haze removal, floor heating, comfort and energy saving.Performance Introductiona. The machine can run heating, refrigeration, hot water, refrigeration and hot water, heating and hot water operation modes.b. The motherboard can set model parameters.c. It has multiple temperature sensors to ensure detailed and accurate sampling of the working state of the machine. All temperatures can be queried and displayed on the main controller.d. Each compressor has high-voltage protection, low-voltage protection, exhaust temperature protection and current overcurrent protection to ensure reliable operation of the machinee. Efficient and accurate electronic expansion valve control algorithm.f. Lack of phase and wrong phase will cause the whole machine to stop running.g. The waterway has safety measures such as waterway switch and low-temperature antifreeze protection.h. Real time timing switch function.Compatible with different kinds of terminalsIn the air source combined supply system, the indoor end system includes fan coil, low-temperature radiator, floor heating, etc.Fan coil can be used for refrigeration and heating, and the heating comfort is poor.Radiators and floor heating are only used for heating.The best combination is fan coil refrigeration in summer and floor heating in winter/* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
