Explore our engineered clean-energy heat pumps, optimized for sub-zero performance in Daedeok Innopolis and residential developments.
Daejeon Metropolitan City, celebrated as the technological epicenter and primary research hub of South Korea (Daedeok Innopolis), is undergoing a profound thermal transformation. Driven by national net-zero carbon mandates, strict ESG targets for government-backed research institutes, and soaring LNG heating expenditures, commercial facility managers and residential developers across Yuseong-gu, Seo-gu, and Daedeok-gu are aggressively replacing legacy combustion boilers with ultra-efficient monoblock air-to-water heat pump systems.
The climatic profile of Daejeon presents distinct thermodynamic challenges. With winter temperatures routinely dropping to -10°C to -15°C alongside humid summers exceeding 33°C, HVAC infrastructure in Daejeon demands robust operational adaptability. Monoblock air source heat pumps equipped with Enhanced Vapor Injection (EVI) technology and natural refrigerants (R290 propane / R32) have emerged as the definitive solution. By integrating compressor inverter modulation with all-in-one outdoor hydronic engineering, these systems provide stable year-round space heating, active cooling, and sanitary hot water up to 75°C without requiring internal refrigerant piping inside the building envelope.
Unlike split HVAC systems that require certified refrigerant technicians to pull vacuum and charge gas on site, a monoblock heat pump contains the entire refrigerant loop within the factory-sealed outdoor unit. Water pipes directly connect from the unit into the building’s hydronic circuit (such as traditional Korean Ondol underfloor radiant heating or fan coil units). This eliminates indoor refrigerant leakage risks, slashes installation labor by over 40%, and satisfies Korea’s rigid safety directives for institutional and high-density residential installations.
Achieving peak Coefficient of Performance (COP) under severe sub-zero ambient conditions requires advanced refrigeration design. As a global supplier and exporter serving the Daejeon HVAC market, Zhejiang PeakWay Pump Co., Ltd. incorporates cutting-edge thermodynamic innovations to guarantee uncompromised heating capacities.
With a Global Warming Potential (GWP) of just 3 and zero Ozone Depletion Potential (ODP), R290 is the ultimate future-proof refrigerant. It exhibits superior thermodynamic properties over legacy R410A, allowing higher ambient heat absorption and elevated hot water production (up to 75°C) ideal for sanitization and high-temperature radiator retrofits across Daejeon commercial facilities.
Enhanced Vapor Injection (EVI) bypasses a portion of gas back into the mid-pressure chamber of the twin-rotary compressor. This process prevents compression ratio degradation during severe winter spells (-25°C), maintaining 100% nominal heating capacity while extending operational life cycle and suppressing motor vibration noise.
Equipped with native RS485 Modbus, Wi-Fi cloud management, and SG-Ready dry contacts, our monoblock units seamlessly integrate with Daejeon’s smart energy networks, solar photovoltaic (PV) setups, and automated Building Management Systems (BMS) to optimize off-peak electricity tariffs.

Expert technical answers to assist HVAC engineers, contractors, and importers evaluating Monoblock Heat Pumps in South Korea.
Monoblock systems keep all refrigerant components inside a hermetically sealed outdoor casing. This eliminates the requirement for certified refrigerant pipe installation on site, prevents fluorinated gas leaks in living areas, and drastically lowers installation labor costs. Water pipes connect directly into the building's hydronic circuit, making it perfect for rapid retrofits in Daejeon residential apartments, office towers, and research facilities.
PeakWay Monoblocks feature Enhanced Vapor Injection (EVI) technology coupled with Panasonic or Mitsubishi DC Inverter twin-rotary compressors. By injecting medium-pressure refrigerant vapor during compression cycles, the system prevents capacity drops in freezing conditions. Additionally, intelligent dynamic defrosting algorithms ensure ice build-up on evaporator coils is cleared efficiently in minutes without interrupting indoor thermal comfort.
Yes, highly safe. Because the unit is installed outdoors as a monoblock, the R290 natural refrigerant remains entirely outside the building envelope. PeakWay units feature explosion-proof sealed electrical boxes, ATEX-certified pressure switches, integrated venting paths, and anti-leak monitoring, complying fully with international safety standard EN 60335-2-40 and Korean environmental mandates.
Absolutely. Our monoblock units deliver steady water flow temperatures ranging from 35°C up to 75°C, matching low-temperature Ondol radiant hydronic floor loops perfectly. Hydronic floor heating operated via heat pump delivers up to 75% higher energy savings compared to conventional electric floor cable systems or gas boiler loops.
Standard manufacturing lead times for bulk OEM/ODM orders range between 20 to 30 days. We provide comprehensive factory warranty coverage on core components (including 3–5 years for compressors), alongside full spare parts kits (PCBs, sensors, water pumps, valves) with every container shipment to support local warranty fulfillment in Daejeon.
