QAHV CO2 Hot Water Heat Pump for Commercial Applications

As a leading manufacturer of air-to-water heat pumps, Mitsubishi Electric have developed QAHV; the latest innovation in their comprehensive line-up of Hot Water Heat Pump products.

Utilising CO₂ as an environmentally friendly, safe and natural refrigerant with zero Ozone Depletion Potential (ODP) and a Global Warming Potential (GWP) of just 1, the QAHV Hot Water Heat Pump is the green, highly reliable and future-proofed alternative to traditional boiler systems for potable hot water.

Specifically designed to produce high temperature potable hot water up to 90°C, the large 40kW capacity QAHV CO₂ Hot Water Heat Pump can be grouped with up to 15 more units to form 640kW of high temperature water production. Making it an ideal solution for commercial and industrial projects where hot water demand is high such as; gyms, hotels, motels, aged care facilities and hospitals.

Due to Mitsubishi Electric's unique technology, the QAHV ensures highly reliable performance as well as high heating capacity even at low outdoor temperatures.

With the future availability of natural gas clouded in uncertainty and the potential risk to occupants if a leak occurs, the QAHV Hot Water Heat Pump offers a safe, low-carbon alternative to gas water heating with higher efficiencies and compact dimensions to minimise plant space.

Key Features

Utilises CO2 (R744) Refrigerant for Low Environmental Impact

  • QAHV adopts CO2 (R744) as it is an environmentally-friendly, natural refrigerant which has zero Ozone Depletion Potential (ODP) and has a Global Warming Potential (GWP) of 1.

Superior Heating Performance Even at Low Temperatures

  • As ambient temperatures drop, so too does the capacity of heat pumps. However, the QAHV is able to provide its full heating capacity of 40kW even at ambient temperatures as low as -3°C. Furthermore, the unit operates to supply 90°C hot water in ambient temperatures as low as -25°C.

High Capacity Unit

  • 40kW nominal capacity of a single unit.
  • The QAHV can be grouped together with up to 15 units to form a bank of 640kW of highly efficient high temperature hot water production.

Better Security of Hot Water Supply and More Lettable Space

  • As a single pass high temperature lift machine, QAHV works best with a high water temperature difference and delivers 10l/min or more of full temperature usable hot water in real time.
  • This directly reduces the amount of storage required to meet the peak demands, and gives quicker recovery. Ideal for commercial uses where hot water demand is high, such as gyms, hotels, motels, aged care facilities and hospitals.

Mitsubishi Electric Flash Injection Circuit Ensures Stable Operation and Helps Meet Legionella Guidelines

  • The QAHV’s superior level of performance is achieved using Mitsubishi Electric’s industry-first Flash Injection Circuit which provides the optimum amount of refrigerant to the system via a compressor through a specially designed injection port. This ensures a highly stable operation that at the same time, meets the guidelines for Legionella.

Patented Mitsubishi Electric Technology Offers Unparalleled Efficiency

  • The Mitsubishi Electric QAHV System utilises a twisted and spiral gas cooler. This patented technology enhances energy efficiency while delivering high temperature hot water.
  • Using twisted pipes as water pipes and running the refrigerant pipes along their grooves helps to increase the heat-conductive area. The continuous spiral groove design accelerates the turbulence effect of water and helps to reduce pressure loss within the heat exchanger, enhancing efficiency.
  • Equipped with the latest inverter scroll compressor, QAHV offers unparalleled efficiency when compared to fixed speed systems - boasting an impressive COP of 3.88*.

*Under normal heating conditions at outdoor temp: 16°CDB / 12°CWB, inlet water temp 17°C, outlet water temp 65°C.

Optional Mitsubishi Electric “BS” Salt Corrosion Protection System Available

  • To help extend the life of the QAHV outdoor unit when located within highly corrosive environments, the optional Mitsubishi Electric “BS” Salt Corrosion Protection System can be applied during the outdoor units manufacturing process to ensure all components are 100% protected before the outdoor unit is assembled.
