-35 Degree Cold Climate Heating Air Source Heat Pump

Principle Introduction The compressor sucks low-temperature and low-pressure gaseous carbon dioxide refrigerant from the evaporator, and compresses the carbon dioxide refrigerant into a high-temperature and high-pressure supercritical fluid through work. The high-temperature and high-pressure supercritical fluid enters the gas cooler to exchange heat with water, and is cooled in the gas cooler. The high-pressure fluid releases a lot of heat, and the water absorbs the heat released and the temperature continues to rise. After the high-pressure fluid is throttled and depressurized by the expansion valve, it absorbs the heat in the surrounding air and evaporates into low-pressure gas through the action of the fan in the evaporator, and is sucked into the compressor to be compressed, so that it circulates repeatedly to provide hot water. Features Natural environmental protection refrigerant: CO2 refrigerant, ODP is 0, GWP is 1, no pollution to the environment, non-toxic, non-flammable; High water outlet temperature: the supply/return water temperature can reach 65°C/45°C, and the highest outlet water temperature can reach above 75°C, suitable for radiators; Excellent low-temperature performance: at -35°C ambient temperature, heating is still normal; High efficiency: the heating performance COP can reach 1.8 at an ambient temperature of -30ºC; Wide range of application: it can work normally in the ambient temperature range of -35ºC~20ºC, suitable for cold areas We can provide bespoke and standard high temperature CO2 heat pump solutions with a range spanning from 6kW to 160kwSystem schematic diagram Technical Pararnetersfor Co2 air to water heat pump for floor heating Unit typeSJKRF-60II/CSJKRF-80II/CSJKRF-120II/CSJKRF-160II/CPower supplyThree-phase five-wire380V/5OHzHeating modeCirculating typeStandard working conditionHeating capacity(kW)5978.5117.1155.2Input Power(kw)24.630.845.560.9Water flow(m³/h )2.032.745.4Low temperature conditionHeating capacity(kW)47.157.188.2116.9Input Power(kw)23.226.440.153.1Water flowm³/h )1.72234Ultra low temperature working conditionHeating capacity(kW)35.643.163.893.1Input Power(kw)20.524.836.753.5Water flow(m³/h )1.221.482.193.2Component InformationSize of water pipe jointDN32DN40DN40DN50Water heat exchangerJacketed heat exchangerAir Heat ExchangerAluminum Fin for copper tubecompressor typeSemi-enclosed reciprocating (variable frequency)/R744Operation PanelColor touch screenMaximum outlet temperature(ºC)75RefrigerantsR744(CO2)/R134aDesign pressure(MPa)High side 10, low side 8(R44)Outline dimensions (length * Width * Height mm)2050x1200x19502250x1350x19502810x1410x21502430x.2250x2000Noise(dB)≤70Weight(Kg)1200150020002700SCOPE of useSupply and return water temperature(ºC)40-65Feed water pressure(MPa)0.05~0.4Water supply temperature(ºC)40~70Maximum flow(m³/h)3468Ambient temperature(ºC)'-35~20Standard operating conditions: Ambient temperature: DB7 °c/wB6 °CInlet temperature: 40 °C, outlet humidity: 65 °CLow temperature working condition: Environment temperature: DB-12 °C/WB-14 °C inlet temperature: 40 °C outlet temperature: 65 °C     Ultra-low humidity: Ambient Temperature: DB-25 °C Inlet temperature: 40 °C outlet temperature: 65 °C                  Usage of the ehat pumps: companies, factories, buildings, school. university, cold climate, etc /* 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
