SANYO GHP - the natural choice

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 drivenVRF systems offers increased efficiency and performance across the range. Now more powerful than ever before, it can connect to up to 48 indoor units.

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

Up to 71kW of cooling from a maximum running capacity of 5

AMPs

Single phase power supply across the range

The option of natural gas or LPG as its main power source

Power supply problems?

If you are short of electrical power, gas heat pump could be the perfect solution.

Enables the building’s electrical power supply to be used for other critical electrical demands.

• Reduces capital cost to upgrade power substations to run heating and cooling systems.

Reduces power loadings within a building especially during peak periods.

Electricity supply freed up for other uses such as IT servers, commercial refrigeration, manufacturing, lighting etc.

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.

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.

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.

What is a GHP?

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.

High efficiency heat exchanger

Exhaust

The ‘M’ series GHP continues to use a ‘hybrid’ heat exchanger for

 

improved efficiency. By interlacing the refrigerant coil with the

 

radiator carrying the coolant from the engine, the condensing

Fan

capacity and radiator performance is balanced to an optimum

 

level. This combination ensures the cooling efficiency drop in

 

cold ambient is kept to a minimum, heating performance is

 

down to -20oc and maintain a high COP.

 

Higher engine efficiency

Air

 

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.

Refrigerant heat exchanger

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

ECO G 3 Way is ideal for the following types of application:

Office buildings with a diverse range of room temperatures due to differing load profiles.

Buildings with computer rooms requiring year round cooling.

Additional parts

By taking its power supply from the nearest indoor unit, the SANYO solenoid valve (change-over box) does not require any additional fused spur and at only 150mm high can be easily installed within a 200mm void space.

LPG option

The option of using LPG as a power supply increases flexibility and avoids the problems of potential site restrictions in the future. The purer fuel is also excellent for further reductions in CO2 emissions - a fact recognised by the government.
