1. Product Overview

MRCH four-pipe modular air cooled heat pump is a multi-functional polyvalent HVAC solution independently developed by Monchrui for buildings with simultaneous cooling and heating demands. It contains two core 130kW single unit lines: standard MRCH130AR and low-temperature inverter EVI MRCH130ARVLH.

Different from conventional 2-pipe heat pumps which only supply cold or hot water separately, this series adopts four independent hydraulic pipelines to produce chilled water and hot water at the same time. Three switchable working modes are available: cooling only, heating only, simultaneous cooling & heat recovery. It perfectly solves conflicting temperature demands in hospitals, constant temperature labs, luxury hotels and shopping malls, eliminating energy waste caused by cold-heat offset and boosting overall heat recovery efficiency.

Modular design removes the need for cooling towers and simplifies piping layout. Multiple units can be combined for phased capacity expansion. Equipped with high-precision electronic expansion valve and intelligent defrost system: standard model fits temperate zones, while low-temperature inverter model with EVI jet enthalpy technology delivers stable heating under frigid ambient, forming all-scenario constant temperature & humidity solutions.

3. 5 Core Competitive Advantages

3.1 3 Switchable Modes, Simultaneous Cold & Hot Water With Heat Recovery

Three operation logics for one-click switching:

1. Cooling Only: Generate chilled water for full building summer cooling;

2. Heating Only: Supply constant hot water for floor heating & fan coils in winter;

3. Simultaneous Cooling & Heating (Core Advantage): The unit produces chilled water for labs/operating rooms while recovering waste heat to make hot water for guest rooms & restrooms. Internal energy circulation avoids cold-heat offset and drastically cuts annual electricity cost.

3.2 Imported 500-Stage PMV Valve + PID Dynamic Temperature Control

Adopts international brand 500-level electronic pulse expansion valve with PID algorithm, adjusting refrigerant flow in real time according to building load. Ultra-small fluctuation of chilled/hot water temperature meets ±0.5℃ high-precision constant temperature requirements for labs & operating rooms without unstable indoor temperature.

3.3 Intelligent Defrost System For Stable Low-Temp Heating

• Standard version: Timing intelligent defrost judges defrost cycle by ambient humidity & temperature to reduce unnecessary power consumption;

• Low temp inverter version: AI multi-dimensional defrost collects ambient temp, water temp, system pressure & runtime data to stagger defrost without heating interruption, ensuring continuous heating in northern winter.

3.4 Flexible Modular Parallel Connection & Phased Expansion

Single unit nominal capacity:130kW, combinable with 1/2/3/4/5 units freely as below:

Clients can install basic modules first and expand capacity later to lower upfront investment. All combined units work under unified group control; failure of one module will not shut down the whole system.

3.5 No Cooling Tower Required, Wide Installation Compatibility

No supporting cooling tower or cooling water pump needed, saving civil construction & outdoor pool investment. Units can be placed on rooftops, ground equipment zones or building corridors. Only concrete vibration-damping base is required with simple piping layout, ideal for sites without space for cooling towers or water shortage areas.

4. Standard Installation Specifications (Key Notes)

1. Mandatory Vibration Damping Base

   Concrete foundation + rubber dampers must be installed under each unit. Do not rigidly connect air dampers, external electrical boxes and water pipes to ground, otherwise damping effect will fail and noise will be amplified.

2. Noise Control Layout

• Keep distance from noise-sensitive areas: guest rooms, meeting rooms, offices;

• Rooftop units shall not be placed close to building edges to prevent noise transmission to lower floors and complaints;

• Additional sound insulation structure is required for pedestrian-heavy public zones.

1. Airflow Clearance

   Sufficient ventilation space must be reserved at fan outlet; walls & equipment shall not block airflow. For corridor installation, place fan side towards windows/doors to guarantee heat dissipation circulation.

2. Maintenance Access

   Reserve service space around the unit for regular replacement of filters, valves & compressors.

5. Main Application Scenarios

1. Medical Facilities: Hospital operating rooms, ICU, testing labs requiring simultaneous cooling for operation areas and heating for wards;

2. R&D Laboratories: Constant temperature & humidity labs with year-round cooling for equipment and heating for space;

3. Luxury Star Hotels: Synchronous heating for guest rooms, summer cooling for lobbies and hot water for swimming pools;

4. Commercial Complexes: Shopping malls, cinemas & restaurants with separated cold/heat demand zones;

5. Northern Heating Renovation: Low-temperature inverter model replaces boilers to meet process cooling and building heating at the same time.
