Under the background of the profound integration of global energy transition and low-carbon living concepts, residential heating and cooling heat pumps have already become foreigners’ first choice when they buy heating and cooling facilities. TENESUN has already deeply involved in air-source technology for more than 20 years.Our residential heating and cooling heat pumps,such as SMART PLUS series,have already gained a favourable market reputation in many countries and regions depending on their extreme cold adaptability, ultra-high energy efficiency and intelligent&convenient experience. Our machines’ core advantages are shown on their comprehensive leadership in technological breakthroughs, energy efficiency performance and scene adaptation.
Extreme-Cold and Intense-Heat Technology and Breaks Through Climate Limits
The key competitiveness of TENESUN heating and cooling residential heat pumps are their super adaptability to extremely low temperature environments.It has been already rigorously verified in Mohe Extreme Cold Test Base by HuanNeng National Inspection.The machine can operate stably within an ultra-wide ambient temperature from -38℃ to 46℃. Even in Mohe’s extreme cold -40℃, it can still maintain a return water temperature to 47.5℃, ensuring a stable indoor temperature above 26℃ and achieving the highly-efficient heating performance of the temperature difference exceeding 80℃. This function is profited from the support of three key technologies: Firstly, it adopts a renowned brand's low-temperature exclusive EVI compressor with an economizer design, rapidly improving compression efficiency in low-temperature environments to ensure heating power output. Secondly, the advanced heat exchanger with three rows of high-density finned heat exchangers has significantly increased the heat exchange area, enhancing the heat absorption efficiency in low-temperature environments. Thirdly, the patented intelligent defrosting system (Patent Number ZL 2010 1 0523230.8, etc.) accurately judges the frost status based on multi-dimensional data such as ambient temperature, ring-fin temperature difference and so on, achieving "defrosting only when there is frost, and not defrosting when there is no frost." During the trial operation in Mohe in December, it has even achieved "zero frost" and completely solved the defects of frequent defrosting and heating interruptions with traditional heat pumps at low temperatures.
To those families living in frigid areas such as Northern Europe and Canada, this technological advantage completely breaks through the traditional perception "extremely cold areas can only rely on gas heating." Actual measurement data from local customer in Mohe, the northernmost region of China, is shown that one set of 17kW SMART PLUS heat pump can heat a 70-square-meter house. Even during the coldest days in winter, the indoor temperature can remain stably at about 25℃, fully meeting the heating needs of high-latitude areas. At the same time,under the working conditions of ambient temperature -28℃ and an outlet water temperature 41℃, the machine has achieved a measured average COP of 2.49, exceeding the product's nominal low-temperature heating COP by more than 6%, far surpassing the low-temperature energy efficiency levels of similar products in the industry.
CLASS++++ Energy Efficiency Benchmark,Extreme Energy Saving and Consumption Reduction
As one of the first companies in the industry to propose and achieve FOUR CLASS++++ energy efficiency,TENESUN SMART PLUS series’ residential cooling and heating heat pumps have passed the rigorous audit from "CRAA Multi-Condition Energy Efficiency Label Certification Rules" and become the first products to pass the T/CECA-G 0356-2025 "Technical Specifications for FOUR CLASS++++ Energy Efficiency Residential Air Source Heat Pumps".Its energy efficiency advantage is throughout all working conditions: achieving above-Level 1 energy efficiency under different conditions such as heating at 35℃, 41℃ and 50℃, while its cooling performance also meets the Level 1 energy efficiency standard. Under the standard working conditions, the machine's COP (Coefficient of Performance) can reach as high as 4.5, meaning that consuming 1 kWh of electricity can convert into 4.5 kWh of heat, saving more than 70% energy compared with the traditional electric heating and more than 30% energy compared with the gas-fired wall-hung boilers.
To those customers in overseas regions with high electricity prices, this energy-saving advantage directly leads to the significant cost savings. Taking a typical European family of three as an example, using a 12kW TENESUN residential heat pump,it consumes approximately 1800 kWh per heating season. Based on the local electricity price of €0.3/kWh, the annual heating cost is only €540. But the traditional electric heating is 6000 kWh per year and its cost is more than €1800, resulting in a saving of €1260 annually. Furthermore, the equipment adopts a full DC inverter design, with a DC inverter motor matched with the latest control module, offering a higher capacity adjustment precision. It can automatically adjust the operating power according to changes of indoor temperature, avoiding energy waste caused by frequent start-stop cycles, and its energy efficiency advantage is more highlighted when operating under partial load.
