Heat pumps are devices that extract heat from the outside environment (heat source: air,ground and water) and transfer it to a heat sink. They can cool and heat the inside environment using the same refrigeration system. There are several types of heat pumps such as air source heat pumps, ground source heat pumps, water source heat pumps, and composite heat pumps. These heat pumps are installed across a spectrum of buildings such as Commercial buildings, Information Technology (IT) Parks, Hotels, Restaurants, Manufacturing Industries, RetailOutlets, Public buildings, and Residential buildings for enhanced lifestyle comfort.The Heat Pump market in China is one of the fastest growing engineering markets in the country.The Heat Pump market in China is highly competitive with the presence of several local and international vendors. Some of the prominent vendors in the market are Daikin Industries Ltd.,Sirac Air Conditioning Equipments Co. Ltd., Trane Inc., and Gree Electric Appliances Inc. The market is expected to witness an improvement in its growth rate and post a CAGR of 27.66 percent during the period 2012–2016.

A diesel engine is a machine that converts chemical energy into mechanical energy by the method of high-pressure internal combustion. Mechanical energy enables the movement of pistons in a cylinder in the diesel engine, which in turn facilitate the movement of a crankshaft. A diesel engine is composed of several components such as fuel injector, piston, connecting rod, crankshaft, and combustion chamber. Unlike petrol engine, diesel engine does not have a spark plug for igniting the fuel. Diesel engines are used in several industries such as Automotive, Aerospace, Shipbuilding, Machinery, and Locomotive. In addition, these are increasingly used for power backup. Diesel generators are also deployed across residential, commercial, and industrial buildings for uninterrupted power supply. Diesel generators are incorporated with agenhead that produces electrical output from mechanical energy developed in the engine and works under the principle of electromagnetic induction, generating electric current from diesel engines.

Internal combustion engines convert chemical energy into mechanical energy, which can be used in several applications. For instance, in a car engine, the combustion of fuel creates mechanical energy, which enables the movement of the pistons. The movement of pistons in turn creates a rotary motion, enabling the rotation of wheels. Based on the fuel used, internal combustion engines are classified into two major categories: diesel engines and gasoline engines. These internal combustion engines are used in almost every Machine Manufacturing industry such as Agriculture Machinery, Engineering Machinery, and Marine Engineering. They are adopted by manufacturers across the industries for manufacturing various machinery such as car engines, truck engines, heavy-duty vehicle engines, cranes, marine diesel engines, and electric generators.

Pumps are machines that are used to transfer liquids from one place to another and also to facilitate circulation of liquid around a system to increase the operational performance of industrial plants. Thus, pumps enable operations such as circulation of coolants or lubricants throughout machines and other equipment. Pumps are divided into two main categories: dynamic pumps and positive displacement pumps. Pumps are widely used across the globe by various industries such as the Mining, Oil & Gas Production, Oil Refining, Chemical, Power Generation, Food and Beverage, Machinery, Aerospace, Shipbuilding, Automotive,Pharmaceutical, Pulp and Paper, Marine, Water & Sewerage, Agriculture, and Construction industries.The Pump market in China is one of the steadily growing engineering markets in the country. The market is highly competitive with the presence of several local and international vendors. Some of the prominent vendors in the market are FengQiu Group Co. Ltd., Shanghai East Pump (Group) Co. Ltd., Tianjin Rongheng Group Co. Ltd., and Shanghai KaiQuan Pump (Group) Co.Ltd. The market is expected to post a CAGR of 10.69 percent during the period 2011–2015.
