Introduction

Water to water heat pumps (WTWHP) is a method that is being used to make constructive use of the heat. One considers this method to be constructive and effective as energy saving occurs substantially along with a decent amount of return on investment. Numerous large institutional and commercial facilities require hot water for their work purpose. The range falls between 46 degree Celsius to 77 degree Celsius, and this range of hot water is essential for their usage. This article discusses how “Energy Standard for Buildings except Low-Rise Residential Buildings” is attainable through condenser water flows and exhaust air streams that are being used as heat sources in certain circumstances. Another possible source is process fluid flows. Heat sinks may include outside airstream, domestic hot-water flows, and process fluid flows.

This article will be providing a useful and comprehensive discussion of how it can be attainable. Mechanism of heat pump involves taking from a low-temperature source and then raising its temperature to a level that is of considerable use. There are refrigeration systems, chillers and air conditioners that all are apt for the above definition, but the heat that it usually gives off is not made use of. The word heat pump is used for equipments which are generating heat at higher temperature and can thus be used for future effectual means. One can explain this through example such as where applications of residential are of concern; heat is pulled through an air-to-air heat pump (American Society of Heating, 2007).

One can explain this through example such as where applications of residential is of concern, an air-to-air heat pump pulls heat from the air that is outside at the time of the heating season which further pulls up the heat's temperature to a position that can be utilized to warm the inner area. For the same usage, residential ground source heat pump heaves heat from the ground for exactly similar reason. A heat pump allows a transfer of heat contained air, land or water to heat or cool a building. The energy then produced is called geothermal energy because it comes from the energy of the Earth. There are two main types of heat pump that are open loop and loop closed. Both types have both advantages and disadvantages. The choice undoubtedly depends on environmental characteristics. A heat pump closed loop makes a transfer to or from an area of water surface with a coolant flowing through the pipes. This type of system is immersed in water, for example, in an artificial pond. A heat pump open loop can suck water from a source located at the surface and then passed through a heat exchanger heat before discharge into surface water body or storm sewer. Heat pumps driven by surface water does not contain risk to the environment if they are manufactured, installed and used properly.
