■ The preceding nominal cooling capacity is measured in the
following conditions: the indoor dry/wet bulb reads 27°C/19°C, and
the inlet/outlet water temperature is 30°C/35°C.
■ The preceding nominal heating capacity is measured in the
following conditions: the indoor dry/wet bulb reads 20°C/15°C, and
the inlet water temperature is 20°C.
■ The unit noise is a sound pressure level noise value measured
through test in a semi-anechoic room according to relevant
■ The unit performance parameters are subject to change due to
product improvements without prior notice. The parameters on the
product nameplate prevail.
■ For details about on-site power distribution and wiring for unit
installation, see the nameplate or installation manual of the unit.
EKWH series water (ground) source heat pump packaged unit has many
features such as complete models, high efficiency, low noise, easy
installation, and easy maintenance, and provides high air supply
static pressure. It can send air over long distance through the air
duct. Certain models can regulate the air supply direction to adapt
to field installation. The packaged water source heat pump
is applicable for various places such as commercial plaza, factory,
hotel, and office building.
EKWH overall water (ground) source heat pump packaged unit has a flexible structure. For example, EKWH008A(R)~EKWH070A(R)
series is designed for ceiling mounting. The air supply direction
can be changed from front air supply to side air supply. The
EKWH180A(R)~EKWH350A(R) are horizontal/vertical and can be ceiling
mounted or floor mounted. The air supply direction can be changed
Compared with a split-type water source heat pump, packaged water
source heat pump is easier to install. It runs as long as the
circulating water pipe, air duct, and power supply are connected
without installation of the refrigerant connection pipe and
indoor/outdoor unit signal lines, greatly reducing unit hoisting
The use of building automation (BA) systems is more and more
popular. The BA systems make remote device management possible, and
can efficiently improve the device utilization rate, shorten the
maintenance time, and save energy. EKWH series packaged water
source heat pump provides intelligent RS485 interfaces for easy
network connection. All units provide optional power off memory and
self start upon power recovery.
In a place with large story height, for example, a mall or factory,
the large-scale integrated water source heat pump can be easily
designed as a full air system to greatly reduce the number of air
conditioning units and facilitate centralized management. The air
conditioners can be installed in the equipment room or ceiling
Higher Energy Efficiency
EKWH series water (ground) source packaged heat pump unit uses
select world famous brand compressors and high-efficiency inner
thread coaxial tube-in-shell heat exchangers. Through fine
matching, the average cooling energy efficiency ratio can reach
over 4.0. Certain units provide a cooling energy efficiency ratio
of more than 4.5. For a large-capacity cooling unit with over 10
hp, parallel design for compressors is adopted for higher
reliability and energy efficiency.
EKWH series packaged water source heat pump is designed with
multiple security protection functions. In addition to regular
under-voltage, over-voltage, and overload protection, the following
protection functions are provided: pressure protection of the
cooling system, protection against water flow cutoff, and
protection against over-temperature of the circulating water. In
addition, the controller provides sound, light, and code alarms to
report fault and protection information in a timely manner.
