Gas Heat Pump M Series - the perfect solution when you’re short of power
SANYO has been developing GHP VRF systems since 1980, during which time we have been committed to delivering ground-breaking technology. As a result, the commercial range of GHP VRF systems is leading the industry in the development of efficient and flexible systems, making them the natural choice for commercial projects, especially for those projects where power restrictions apply. As you would expect, all of our gas driven VRF systems have the highest reliability rates in the industry and a leading customer service programme.
The M Series of gas driven VRF systems offers increased efficiency and performance across the range. Now more powerful than ever before, it can connect to up to 48 indoor units.
SANYO benefits
High-efficiency operation
13-25 HP models are equipped with a high-performance air exchanger and a newly developed refrigerant heat exchanger for high-efficiency operation, making them one of the most energy‑efficient solutions on the market.
Lowest nitrogen oxide emissions
The GHP VRF systems have the lowest nitrogen oxide emissions, 66% below the standard. In a pioneering development, the SANYO GHP features a brand new lean-burn combustion system that utilises air fuel ratio feedback control to reduce NOx emissions to an all-time low.
The application principle of Variable Refrigerant Flow (VRF) systems for projects with multiple indoor unit is now very much an integral element of the UK air conditioning market place.
A GHP is no different in principle, however, developed by SANYO in 1980 the GHP outdoor unit is fitted with a combustion engine, powered by Natural gas or LPG, to drive the refrigerant compressor.
Variable capacity is achieved via the engine speed being altered up and down just as an inverter compressor speed is controlled in the electric VRF equivalent. The GHP therefore is an ideal solution where electrical power is at a premium (or no 3 phase available) however it also boasts a number of additional benefits/functions that are not available on an electric equivalent.

Improvements include increased part load performance, reduced gas consumption with a Miller-cycle engine and reduced electrical consumption from using DC fan motors.

Excellent economy
The SANYO GHP provides quick and powerful cooling/ heating and increases delivery of heat into the space by the efficient recovery of heat from the engine cooling water, which is injected into the refrigerant circuit.
In addition, the use of engine waste heat ensures that our gas heat pump air conditioner requires no defrost cycle, therefore

providing continuous 100% heating performance in severe weather conditions with an outside air temperature as low as -20°C. During cooling mode the rejected heat from the engine is available for use within a hot water system and can supply up to 25kW of hot water at 75 °C.
High performance
With its advanced heat exchanger design, this new GHP system offers improved efficiency and reduced running costs, which, coupled with improved engine management systems, have greatly improved the system COP rating.

By utilising a Miler-Cycle engine, the compression stroke is reduced and therefore pumping losses are minimised. As a result the expansion volume ratio increases and the efficiency improves.
Miller cycle: This heat cycle has the characteristic that the closing time for the suction valve in regard to the base engine is late. As a result, the expansion stroke becomes relatively longer in comparison to the compression stroke.

New electrical power generator model
The biggest breakthrough in recent GHP technology is the launch of the ECO G Power, which provides 4.0kW of power. That’s enough electricity to power 8 computers or other applications.
By fitting a new plate heat exchanger the engine waste heat is recovered efficiently and reused to improve performance. In addition a proportionate control 3 way change over valve is used for control of the engine cooling water to increase efficiency in heating operation
