Tyneham natural refrigerant commercial heat pumps
15kW – 65kW outputs available
R290 natural refrigerant
Achieve high up to 75ºC
flexibility, making the system particularly suitable for buildings such as hospitals with mixed use spaces and varying degrees of temperature and seasonal fluctuations. As well as flexibility other key advantages include higher efficiencies which lowers operating costs, simplified plant design therefore reduction in installation & maintenance costs and time, and a reduction of CO2 emissions compared to more traditional heating and colling systems.
The NRP is a multi-function unit that can accommodate simultaneous or independent
production of low temperature hot water (LTHW) and chilled water (CHW). The inclusion of compact axial fans enables high airflows with low static pressure and the use of scroll compressors offer excellent efficiencies at partial load – ideal in hospital with variable demand and provide reduced sound emissions – quieter than reciprocating compressors. The NRP’s high yield, low electricity absorption and ability to help meet the low carbon requirements of the brief offered significant advantages over other products.
Hot water and a/c
The 4-pipe Air Source Heat Pumps (ASHP) unit generates primary temperatures of 45ºC in heating mode and 6ºC in cooling mode. The equipment is connected to a thermal store for each water medium to provide the required cooling and heating. The chilled water thermal store is also connected to the mechanical ventilation cooling coils. The low temperature hot water thermal store also serves the mechanical ventilation heating coils, underfloor heating manifolds and duct mounted heater batteries. The heating circuit has also been extended to serve two indoor WWB water source heat pumps (WSHPs) to enable generation of domestic hot water up to 80°C and arranged with a thermal store. The WWB produces high temperature water from a low or medium temperature source,
directly or indirectly via a cascade arrangement. It has been designed with the aim of guaranteeing high efficiency at full and partial loads. The units wide operating range enables integration with numerous applications and can be used as an alternative to boilers and conventional systems that are used to produce high temperature hot water. The WWB is designed with highly efficient compressors and the plate heat exchangers have
reduced pressure drop. There are two independent heating circuits which ensure maximum reliability of the system and electrical panel. A slide-out system enables the unit to be opened from the right or left. An additional NRG air source heat pump serving the low temperature hot water system
(LTHW) is being used to maintain the temperatures of the system during peak winter conditions, and acts as redundancy, ensuring continued operation of the building. The NHS’s goal is to be a low carbon, climate resilient health service that yields significant health benefits for the communities it serves. The Haywood Hospital is a prime example of what can be achieved and provides a benchmark for others to follow.
